Fender Pro Tube Pro Reverb - Dead Tremolo and Noisy Reverb

[pmwalk]

Hello All,

I new to this forum, but I hope you kind people will be able to help?

I have a Fender ProReverb which appears to have an issue with the tremolo, it's not working at all! and the reverb now sounds noisy.

Both defects occurred at the same time, so appears to be the same underlying issue. I'm just not sure what it is.

Are there any user replaceable parts (tubes etc) that I should be looking at specifically for this issue. I have gone through the preamp tubes and replaced one at a time with a new 12AX7.

The only thing I have not done is looked at trying new Power amp tubes. The indicator LEDs are showing that the Tubes are OK.

Just wondering if anyone has had a similr issue and could point me in the right direction to repair the problem.

Thanks

Paul Walker

Both the reverb driver and trem oscillator are fed from the 'Y+' power supply node (it feeds other stuff also though) - maybe C206 needs replacing?

What kind of noise is the reverb making?
