I decided to do a cap job on it, but decided on making a new board for it. I'm almost through wiring it and will load the board soon. http://i70.photobucket.com/albums/i115/teleamp/100_1262.jpg JohnnyCrash July 14th, 2008, 08:11 PM Sweat! More amp pr0n photos!!!! teleamp July 15th, 2008, 01:10 AM Getting close! http://i70.photobucket.com/albums/i115/teleamp/100_1265.jpg This one should sound sweet if I get the right speaker. I changed the RCA speaker jack to a 1/4" phone jack so that I can use it with other cabinets as well. This should be a sleeper grab-n-go. 51Esquire July 15th, 2008, 01:19 AM Nice job! eggman July 15th, 2008, 01:31 AM Howdy, I'm happy for you. No Fender amp sounds better for raunch than a VC! Enjoy. Eggman JohnnyCrash July 15th, 2008, 02:10 AM It could be my eyes, BUT that looks like a dual Octal push pull... Both octals have screen/grid resistors on them, the board seems to have a PI bias/grid feed on the far left, SS diode rectifiers directly from the PT to the cap-can (a lack of them rows of vibro caps, NO it looks like some Mallory's in a row there in the middle, hmm)... So... WHAT IS THIS THING? A Princeton rebuilt from a Champ? I guess I should zoom in and eyeball that layout and resistor color bands, but I have a feeling suspense is the name of this build :) teleamp July 15th, 2008, 02:22 AM JC nailed it. I am doing a ss rectified AA964 Princeton circuit in it. I had a cool old OT and this wasn't a spectacular Champ. http://i70.photobucket.com/albums/i115/teleamp/100_1263.jpg I'm going to stay with an 8" speaker, I think I'll try a Weber Sig Alnico, I'll be running it at its ragged edge. jaydawg July 15th, 2008, 07:09 AM Oooooohhhhh..............Too cool.

Are you going to beef up the preamp since you're going with a non-Reverb Princeton? SamBooka July 15th, 2008, 12:35 PM Ah.. so that explains the new board. What are you using for the pi?
