  1. Sorry to hear of this incident and an obviously misguided law. Lane splitting is illegal in Mass. and I rarely see any egregious violations. As an occasional rider I wouldn't even consider doing it. There are just too many uncertainties that get introduced very quickly.
  2. Happy Birthday Greg. Thanks for keeping this thing going!
  3. The LP version is not the box-set. If you select the LP you will see the CD that matches the LP for $9.69US.... 12 songs. The box set for $341.33US contains 18 CDs!
  4. I guess Pink Floyd is already represented with "The Wall", but personally I like "Animals".

    fluid film

    I did this in my driveway with a set of ramps. A lift would be much better. I used a $14 gun from Amazon paired with Home Depot HDX wide mouth bottle ($2.68) which screws right on. The stuff has the consistency of mayonnaise so it's a bit difficult to get into the bottle. My compressor only has a 4.2 gallon tank so needed to go slowly. Most of the more detailed videos show the use of a wand to get into tight spaces. I didn't do that. Avoid the exhaust as much as possible as it takes a while to burn off.

    fluid film

    Anyone living in the snow/rust belt tried Fluid Film? I have an 8 year old truck and the undercarriage is rusting to sh!t. I've never liked the idea of sealcoating, but this is different. Some good testimonials/videos on the Tube. I applied this today and the job went smoother than expected. Not sure why I didn't do it sooner? This is a weekend and foul weather vehicle for me ... 2011 with 48K miles. Will last me a long time if I can arrest the rust.
  7. Glad to hear that things are heading in the right direction!
  8. Thats an excellent cabinet. I bought a pair for Sunfire HRS10 drivers. Very happy with the product. I was not too keen on the radiused face so I bought a piece of 2'x2' mdf at HD for $6 and cut new faces.
  9. Nice karma ..... someone gonna have some new toys.
  10. So far so good Greg - Thanks!
  11. I tried this with a 10K pot on one channel, the other channel got full signal. I did not test for audio quality, etc.... I simply did a freq response test from 20Hz to 20KHz with a function generator connected directly to the amp, no preamp. Since a C-1 has 200ohm series output resistance, I included 220ohm in series between the func generator and the input on EACH channel, considering this a typical application. I ran 2 sweeps, one sweep with the pot all the way up, the other with the pot trimmed about 1/2 scale. Output level on the straight thru channel was about 3Vrms, input was at 100mVrms, dummy 8ohm loads on both channels. For the straight in channel, the gain was nominally 29.8dB with a variation of only 0.28dB. Set at full level, the channel with the pot was nominally 29.2dB with a variation of 0.27dB. The 220ohm and 10K pot make a voltage divider 10K/10220= 0.978. This would account for some of the difference. Note that the gain in this channel might be slightly less to begin with, I never went back to check without the pot. Set at about 1/2 level the attenuated channel was nominally 23.0dB, so about 6.2dB down from the full scale of 29.2dB. Makes sense as 1/2=6.02dB. Variation was a bit higher, 0.37dB, still excellent flatness over the audio range. So - from a freq response standpoint - this looks good. As mentioned, the grounding on these inputs is sensitive, your ears will tell you if the pot adds any noise due to ground loop or the like.
  12. Phil - I'm going to evaluate my current receiver over the next few days to see if I can get it to behave. If not, I'm going to kick it to the curb. I've come to the conclusion that I'm going to have to buy a unit with output amps. The processor/pres are just too expensive. Manufacturers clearly want us to buy a unit with amps, so I'm not going to fight it. My 5.1 speaker setup isn't expanding any time soon, so anything more than 7.2 is way in my future (I would need a new house even to get to 7 speakers). The Denon AVRX3500H at $500-600 seems to cover my needs and is on my short list if I have to buy something soon. I have no experience with this unit so if anyone does, it would be nice to hear about it.
  13. Just the pots. I got my dead amp up and running last night. I didn't look at the pots I have, but I think they are 10K based on an old Mouser order. I think 20-50K might be a better option, but as was previously mentioned, a pre-amp like the C-1 should not have much difficulty
  14. Great Karma. I'm out as I have a BillD for sale ....
  15. Yup - I have not used the Yamaha amps in years so I figured a pre-amp processor would be the ticket as I'd like to get more current on HDMI capabilities. I was shocked by the cost of these units. My Yamaha preamp output levels are somewhat lower than other units I've used in the past, but are sufficient for my needs.
