  1. Hi Nahash do you have a service manual for Sunfire TGA 7201 theatre cinema grand amplifier ?

      I don't have anything publicly available yet.

  2. Greg,

     

     I have a question that I trust you will have the best response for . Recently, I recapped an old rack ear C-9 along with replacing the RCA jacks. It worked just as expected and I was happy with it, so I sent it back to the customer. When she got it, she says that when switching in or out the narrow/wide button causes a pop. That was not the case for me at all. I want to know, having not heard that happening before, is there any idea that you would have as to what might cause this, and does it matter if the pop is little anyway? I don't want to do the wrong thing here, but I also don't want to chase ghosts if there is even a reason to.

     

       Thanks, Greg

      The narrow/wide switch is located in the early stage of the SH circuit, and so it tends to be a rather sensitive area for a mechanical, bouncy switch to introduce some noise. It's not uncommon to hear a light 'pop' on many SH iterations from this switch, so I personally wouldn't worry about it.

       

      Some people can be picky about such things though.

  3. Hi guys, I had a couple pictures of my bias millivolts and where I took those readings. I can’t figure out how to upload the pics from my photos to the site. Can someone assist this possibly technology challenged soul lol? Thank you in advance.

      @Joe C You need to reach the rank of Novice. You're still an Inbound. I'll fix that.

  4. Greg,

     

      I expect that you are quite busy at Nelion. Still, I have to ask if you would be interested in working on a Glassware Audio phono pre that has an issue. The trouble has already been narrowed down, but the tech presently working on it has hit a brick wall with Mr. Broskie, the designer of the amp. Mr. Broskie has been really lean on replying to emails, and when he does, the replies are one sentence or so. Not the help needed to troubleshoot his product. This has gone on for months, and I am almost ready to ask for the amp back. But, then what? I have some serious cash invested already. If you have interest, then I could have it shipped to you from Florida, where the amp is sitting right now. Or perhaps you can recommend someone for this repair. 

     

      Thanks, Greg

      Hello,

       

      For the time being, yes, I'm booked solid. What sort of trouble are we having? What is it about this unit that makes it so hard to troubleshoot? Schematics available?

  7. Hello all,

    Merry Christmas from warm (54 deg F), rainy Winthrop. Snow is about washed away.  Regarding my music system -  since I am 81 and wear hearing aids, the best in the world is no longer needed. I certainly couldn't tell speakers apart as I could 30 years ago. I do have good hearing aids, though. Starkey wireless (but not the newer Bluetooth ones) XINO 110. The frequency response has about 6 channels. Can be set for 4 different response curves. The curve I use at symphony is essentially flat from 20 to about 15k Hz. I can hear timpani and piccolos.

    I want to get the Carver TX-11 working so I can get better FM response than the Rotel receiver.

    The problem is that the manual that came with my TX-11 does not remotely resemble the TX-11 owner manual I downloaded from this site. Also the service manual does not reflect my unit. The service manual shows that the tuner has 2 crystals, X501 and X502, and 2 trim capacitors, TC502 and TC507.  My tuner has only 1 crystal and a single trim capacitor of a completely different shape than the ones shown in the various repair pages here and on YouTube.

    Am I at a level that I can upload photos of the PC boards, and a scanned copy of my owner manual?

      Good job!

       

      You need an o-scope to adjust the refence frequency amplitude for the tuning controller.

       

      By probing Pin 2 of the TC9147BP IC to a ground refence, adjust TC-501 for maximum amplitude.

       

      Pins 2 & 3 are the X-tal oscillator reference circuit.

      Interesting. But you know, it could be a transitional unit. It could be an 11a, but not fully transitioned with the labeling.

      Hello,

       

      Sounds like you have a TX-11a or b. Try downloading the TX-11a service manual and compare.

       

      There aren't any security restrictions on manual downloads.

  10. Hello!The Carver M1.0t is sounding wonderful!The other day I turned it on and there was a very loud buzzing,vibration coming from the transformer??Kinda scared me!!Today turned on and all is fine.Not sure what might have occurred.Wondered if you had ever experienced this event or had other customer’s experience this.Thanks for any information!

    1. Nahash5150

      If you turned it off, then after just a couple seconds or minutes turned it back on again, it tends to bark a little louder when it starts up.

    After falling in love with the sound of some B&Ws at the audio shops, I hunted these down on Ebay. Went with the DM 303s with an LCR-3 center channel, the DS6 THXs are coming in tomorrow for the rears!

  22. I have been reading the CF amp build thread with some outside interest. On one hand, I find it to be a simple build, and I like that. Then there is the pure fact that even simple must be done correctly to avoid serious consequences. That is the parallel that is useful for me. You see, I am attempting to work on a N. Pass design from years ago, that yes, is simple, but unforgiving. Since there is little in the way of information, except for one partial schematic, it is threads, that actually are just that, threads of a bit of usable info here and there. In short, I very much appreciate your input as to keeping the wheat from the chaff on these topics. Accurate knowledge is valuable.

      Cool! Which Nelson Pass Model? His work is very interesting.

       

      As for the tube build thread, I'm glad you found it informative. There are many ways to do things, and properly understood, many are valid...and some not so much.  :D
