Help/Question About Peavey Solid State Reverb Hum

[Lamf77]

So I went to check out a Peavey Stereo Chorus 210 today...seller was selling at a really good price. All worked...except when I turned up the reverb...a terrible an loud hum/drone. Now I have tried amps, where the reverb was spotty or absent...just replaced the tank. I was wondering if a loud hum could be something in the wiring or grounding of the amp? Again, when the reverb was turned down it worked fine.
Now not a lot of specifics, but hoping someone may help....thanks!

Can be on of a few things:
- Input and Output cables are reversed (most common).
- Same cables have a poor connection.
- Reverb springs in the tank broke and are touching the shell, or the tank is upside down from its intended mounting position. Be mindful of the
tank code if replacing the tank, as some are designed for tubes and some, for solid state.
- Recover circuit went bad (least common).

Made an offer of $50 and he accepted. Lets hope it's an "easy" button fix. Thanks!

That was a good buy. I am not a SS guy these days but from 1980 to 1995 all I had was little SS Peavey amp and Peavey T25 guitar. When I decided to start a band before I was too old, I was foolish enough to think I needed a Fender and not a Peavy guitar. I sold it and got a Mexican Strat. I never bonded with a Strat. To this day I do not like a Strat but I sure did like that Made in the USA Peavey. Lately I have priced them and they are not cheap.
