  1. Well well... It's been 3-4 months since I've logged on to the site, and the first post I open is the exact thing that drove me away. Can anyone say "cronies" :-) Jim, I commend you for , stating, and acknowledging the unspeakable. "To say that Russ modified Riches design.. Modified the modification? Again where's the claim to rights or liability ? The original design was Bobs and everyone involve is hacking up his design for their own purpose and product in actuality...". Be careful Jim, my observation is that you're either in or out, determined by a small group. At the risk of wasting my (and the cronies) time, I am perplexed that anyone would even bring up Mr. Kall. From the perspective of a newcomer just wanting to get up to speed on the forum and members. I made the mistake of going back and reading the interchanges from this period. It really was a mistake on my part, as it really change my perception and outlook, bringing in the focus what I've referenced as the "core cronies". No disrespect intended, it's just my perception when stepping back and observing. It's worth looking at with open eyes and learning from our mistakes, instead of bashing me for making the statement. My recommendation, purged it from the site and avoid revisiting it as is being done today. With all that said, I would like to thank the members that reached out and helped me tackle what was the unknown for me, electronics. Providing you keep the blinders intact and you ignore the site politics, the help really gives a sense of camaraderie. If and/or when I revisit, hopefully I will drop into a positive post. I wish everyone, all the best. Will
  2. Thanks for that, my offer stands. All the best, Will
  3. Dom, as always, I appreciate your diplomacy in these matters, and have grown to recognize your defusing calm, as well as the comradery that you seem to infuse into the site. The same applies to any number of members that I’ve had the pleasure of interacting. That being said, I cannot think of one interaction that I have had with Greg that I feel the same. Regarding your synopsis of Greg’s dedication and untiring work, contributions, hierarchy and/or talent, I both recognize and am well aware further to my intense reading of the site archives (out of boredom while overseas). Sadly, this doesn’t change my impression which is solely based on my personal interaction I’ve had to date with the man. Now with that said, I don’t expect for the man to like me. There are some I don’t care for. If for no other reason, I don’t care for the “Cut of Their Jib”. For those, I generally try to either avoid and/or deal with some tactfulness. Advice I would extend to anyone at the helm of any organization. Now at the risk of running long (you can stop reading at this point), I will offer my outlook based on my experience. By no means to bloat, but necessary to obtain a perspective. Up until a few years ago for as long as I care to remember , I owned and managed a multitude of my own oil and gas related drilling companies, strategically placed in some of the most logistically challenging parts of the world. I have had the good fortune to have been associated with the pioneering of an industry, having recognized world-class accomplishments in both technological development, patents (24 in all) and contracts. Despite having a name synonymous in the industry, I do not take credit. Credit is deserved for the engineers and teams I have built, and the people I have surrounded myself with. I have hired over the years, lots of Greg’s. So talented, so much to offer, yet sadly they seldom work out. Their arrogance and inability to be an integral part of a team, ultimately diminishes their value, and if left in place, will diminish the strength of the team. So with the above said, I understand Greg, along with his strengths and shortcomings. I am not implying that this site will flourish or suffer from Greg’s participation, I am only citing my own experiences. The outcome only history will reveal. I will again, say I recognize his unwavering work on the site, contribution and talent, it’s not that that I question. Greg’s first inappropriate response to me, I vowed to respond. After reflecting on the incident, I decided it was not worth my time, or risk of a public squabble, fouling the air within the site. On the 2nd infraction I started to question my decision, could this have been interpreted as weakness? This prompted me to start reading the archives while overseas. What I found is that I was not the first to encounter his unsavory comments and characteristics, and I will unlikely be the last. But I will stand my ground. With that said, I guess it stuck in my craw, and I was likely lying in wait for Greg’s last comments, hence my response. Rather, it was big or small. Lastly regarding “Poking the Bear”, I am not 100% sure who the Bear is in light of the above. If you are implying that Greg is a sleeping Bear, not to be poked, because of his adopted ownership of the site, or that he’s worked hard, rebuilding the site, then so be it. I will gracefully bow out, taking my contributions, as small as they are, elsewhere. If you are implying. Do not awake sleeping Bear(s), well then, I agree. It’s always better to establish a respectful understanding and move on as it does not serve the grater good. But, I will not be intimidated in any shape or form, of late I have participated less and less and if you would like me to retire my membership, I’m happy to do so. Respectfully yours, Will Cherrington PS: I respectfully ask other members to try to forgo the posse mentality, the circling of the wagons each and every time key members are challenged or called to question, or worst or someone simply doesn’t agree with them. In my opinion, this cronyism is so transparent and does not serve the greater good of the site. Squabbles happen, and it’s mediators like Dom that help keep them from getting of hand. Most of us are men, and we are all entitled to our opinions and we should be able to voice it from time to time without being disrespectful . Over the last year, after witnessing this circle the wagon thing, time and again. I have even found myself even laying plants, post, or quotes that I know will generate a reaction just to flush out the wagon circulars and cronyism. Please, can’t we just have an open dialogue without having to run to someone’s defense all the time? We're not a bunch of schoolboys. Again, respectfully asked
  4. Well here you go Greg, anther “Case in Point” maybe you can move it as well. My observation over the last year (as well as reading a number of interchanges you’ve had with others), you’re the type that throws in the brash-arrogant comment, then ends up apologizing (Likely when the smoke settles, and you go back and read your comments) or you let your comments stand to foul the air. Now if you can post yours, post mine. I unlike others do not think the sun raises and sets on Greg. I recognize your talent in electronics, but I've also seen too many of your cheap shots and the effect it has on the site. Not the infamous “Sandbox” that I’ve had the misfortune of reading about I hope… Boy I’ll tell you, if you want to get disenchanted, go back and read about that i.e. the dealing with Russel K., etc.. In my option as somewhat new member, and not being a part of all that squabble , it was a dark time for the site. I for one was disappointed after reading it, as it really exposed some of the underside of the site as well confirming my sediment on one of the deep-rooted members.
  5. And what is this about? "Your content will need to be approved by a moderator" (Sorry for the edit, still trying to figure out this new posting format)

  7. Congratulations Steve, gorgeous!
  8. I think I have figured out what model this O-scope this is O-11 5" Extra Duty Oscilloscope Interesting link for anyone interested in Heathkit info
  9. I agree with that. There is a sense of industrial art to vintage electronic equipment, especially when compared to the same equipment today. It makes you wonder what people think in 50 years about equipment made in 2018. The likely be something intriguing about it, but it will not have the artful, somewhat Art Deco feel to it. Interesting note about Heathkit . We all know them for amplifier kits in the 50s 60s 70s, but what I did not realize is that they made a whole gamut of electronic kits. Everything from O-scopes, multi meter's, amplifiers, one of the first color televisions (a kit mind you), etc. . Imagine sending someone a television and a kit these days...lol The fellow I purchased the tube tester from in Wisconsin is a professor that restores vintage electronics and was telling me he was currently doing restoration on a Heathkit round screen color television, amazing.
  10. I've made a couple of interesting purchases this week that some may find interesting. 1960's Vintage Heathkit Oscilloscope- I'm not exactly certain what model this is as are no identifying markings on the face. I don't think it is a OC-1 (Heath's frist scope) it had a 3" CTR, this looks to be a 5 inch. Will know more once I receive it, hopefully there will be some identifying marks somewhere. My plan is to hopefully turn it into a clock (my skills be willing). Seems to be a couple companies offering PCB kits, converting Oscilloscope to clocks. My goal is not to hack up the unit, some boards-kits appear to be add-ons, not retrofits. Here is one company offering kits. Has anyone built one of these O-scope clocks? Next is a TV-10D/U tube tester. My plan was to pick up the popular TV-7D/U but after doing some research, I think this may be a better unit. We’ll soon find out. One of many opinions was in the following forum- Tv-10 Tester - Bottlehead Found this at all places in Wisconsinafter doing a nationwide CL search. Again, pick up only, but I made the arrangements to ship to California. All the best, Will
  11. With all respect, if it were me, I think I would pass on these. BTW there are a couple pair on eBay. Good luck
  12. Well, as most of you know, I recently picked up a pair of 9t’s to replace the 1.5t still under repair (a whole other story saga). As represented by the seller both amps were an excellent condition, physically and functionally i.e. no thump, hum, etc., except for the meter lamps being out of both units. With the help of Dennis these lamps were quickly ordered to coincide with the delivery of the amps. “dennismiller55: Here is where I get mine: Meter Lamp 12v 250ma” Below is a quick (non-technical) overview of the replacement of the lamps for those who follow and planning their own lamp replacement. That said, I will add that there are a couple of good technical references here in the CS regarding lamp related problems and/or questions regarding changing the lamps to LEDs that I recommend that you seek out using the search function. Sorry, I’m just too lazy to go find them at this writing, to link and reference them. Regarding the twists part of this overview while changing the lamps I stumbled across another interesting problem that will be addressed. With the amps and lamps in hand, I spontaneously decided one evening I would rather head out to the workshop and change the lamps over one more Hallmark Christmas movie (I always know when Christmas season has arrived, as there is no space left on the DVR after the wife has programmed it, something I’ve grown accustomed to over the last 30 years). Throwing the amp on the workbench, I proceeded. There are 10 screws holding the top cover on to the base, 5 on each side. Be careful removing the screws. As I noticed the same problem as referenced in the C1, when removing the cover aluminum shavings were present. So easy out, and easy in, on the screws. Not having opened up a 9t I had envisioned that the UV meter would be attached to the cover, but this was not the case. The meter basel is nothing more than an anodized ring seated in the cover and positioned directly in the center of the meter, which in turn is attached to the base. Ingenious really, and saves the trouble of having to disconnect the meter wires. With the covers off the meter lights are quickly identified just above the meter attached to their own PCB. Note the burnt lamp and lead, you can also easily see the broken filaments. The PCB are attached to the back of the meters with small expansion pens attached the meter, one on each side of the PCB. The Twist: while being my first lamp change on a 9t I was focused strictly on the task at hand, to the point of having blinders on, although I did notice and think it was peculiar, the amount of smoke and vapor residue there was on the back and top of the meter, PCB, etc. but again I was focused on the lamps. Using a small flat head screwdriver gently pop the PCB off the retainer pins. The leads connecting the PCB are long enough that you can position the amp adjacent a small vice to hold the PCB while desoldering and removing the old lamps. Note that the old lamp leads have insulators that can be reused. If for any reason they’re not reusable a small piece of shrink tubing could be substituted (no need to shrink). The insulator tubes installed onto the new lamps. My recommendation is to insert the leads through the pass-through holes, bend the leads to hold them in place but do not solder. With the PCB reattached to the post, position the lamps, re-bending the leads on the backside of the PCB so that you know where to solder them. In my case I decided to extend the lamps to the top of the meter as shown below in the photo. The reason for this is that the only way the light gets to the face of the meter is through the translucent edges. By positioning the lamp behind the meter with short leads, one loses some effectiveness of the lamps and illumination on the meter face. In hindsight, I would cut new insulator sleeves, extending them the length of the leads. BTW , I checked the space above the meter and there’s plenty. You can now remove the PCB and solder the leads in the extended position. Note the extended length after soldering. With the PCB now re-attached to the back of the meter position the lamps directly over the top translucent edge, ensuring that the leads do not touch the meter. Again, extended insulation sleeves are recommended. Reattached the covers, again, use caution as cross threading and over tightening will result in aluminum shavings falling inside of the chassis. The finished product, both meter lamps operational with one caveat. If you will closely look the left-hand meter light is slightly dimmer. The reason this lamp is further back and did not extend directly over the top of the meter as shown above. It was more on the back edge between top and back. Unlike the first unit that was directly over the top. I have since rectified the problem but wanted to point it out. Also in the photo the right light may look to bright but in reality, it is much nicer aesthetically when comparing the 2 in real life. Now for the Twist: at the risk of further exposing my inexperience I realized when opening the first unit that the smoke/vapor residue was out of place, and my common sense told me that a burnt lamp would not produce that type, or volume of residue. That being said, I was again focused on the task at hand, where a more experienced tech would have immediately started seeking the out the cause. As you can see just above 300 ohm resistor the white powder looking residue on the backside of the meter, fanning out and getting wider as you follow it up to the top of the meter. Covering the back of the meter, PCB, lamp, top edge of the meter. After putting this unit back together and wrestling with this image through the night, the next morning I hauled the amp back to the workbench, remove the cover and more closely inspected everything looking for the culprit. What I found, well, “a blind man could have seen, no discredit the blind men” the 300 ohm resistor was sitting down on the top of the plastic meter housing, for who knows how many years. The result was a slow melting of the top of the meter to the point of reshaping it and generating a smoke residue that covered the parts. How someone operated this amp for so long with a plastic burning smell without researching the problem is beyond me. Fortunately, the meter housing was melted and deformed where the resistor pressed against it, but it did not burn through or interfere with the operation of the meter. Simply bending the wire and repositioning the resistor rectified the problem. Again, there are a couple technical pieces I would recommend anyone planning a lamp change to seek out. One was a piece by Greg about substituting LEDs and the issues surrounding it, i.e. change in milliamps. The 2nd was a very good article written about a thump problem and how the lamps may have contribution to this. My apologies to the author I cannot remember offhand who authered it. If someone remembers, feel free to add it or tell me while I can still edit. Good luck with your Carver projects. All the best, Will PS: Oh and Dom, as always grammar checks are always welcome...
