Princeton aa1164 build

[Drgitpiker]

Hi, ive got  a strange problem? I have a diy princeton aa1164 build that has hammond m3 organ transformers. Power xformer voltage was to high with a 5u4, but fine with a5y3. The amp had ghost tones mainly on lower strings. I switched output xformer leads to the plates and the ghost tones went away , but now I have no tremolo. Anyone had a problem like this?

gonna say based on your description above,  a wire got knocked loose, a iffy solder joint failed, foot switch didn't engage,............

No ,it not that I should say there is a very small amount of trem but almost inaudable. Havent tried switching it back yet to see If  the trem returns. Thank for responding .

I should say there is a very small amount of trem

That very small is also a MAJOR part of your bias circuit.
I would highly recommend checking the bias since they are both interconnected by wire

I switched it back , the ghost overtones came back and so did the trem. I tried switching the coupling caps around, ghost tones went away, so did the trem I have adj.bias, tried high and low bias settings, still almost no trem. When I first got the amp up and running, the trem for me was a little weak. I changed the 1m trem coupling resistor to 500k , got it to my likeing, if I spead up the trem to 8 or higher on the speed the trem would fade out intill I slowed it back down, then it would slowly fade back in. Tried a different  tube in v4 ,no change. It seems to be a phase problem.

I guess no one has any idea what wrong with my amp. If I switch xformer leads around on th 6v6's, I have tremolo ,but with nasty overtones and harmonics. Switch it back good amp tone , very  weak trem. HELP !

Forgot to mention, I put the Paul C pi mod from the start, so I never ran the amp with the stock pi wiring. Could the modded  pi cause this problem?

To start diagnosing the problem, we need to see the voltages throughout the amp. (Including the DC voltages for B+ and each HT node, and all the plates and cathodes.) While you’re at it, check the AC voltage on the sockets heater pins.

Well guys it took me a few days, but I found the problem. The cathode resistor on v4a the trem side is a 3.3k. By mistake I grabbed a 33k. At 66 my eyes aint what they use to be. Now I have more trem that I know what to do with. Had another problem that was in the reverb. With the hammond organ xformers my b+ was on the high side, changed to a 5y3 and that helped was getting a buzzing distortion when id hit the strings a little harder. It would get louder when I turned up the reverb. Turned out to be to much voltage on the reverb xformer. Moved from the b to c node , no more buzz. Got this amp all biased in. It sounds killer. With all that overkill Hammond iron, it has headroom for days , no sag in this power supply,its on a double dose of viagra !  LOL Thanks for the responces.
