    Picked this amp up for $20 at local second hand store. The chorus is working fine but the reverb is not there...just makes the static hum of the amp louder when turned up. Both red and black cables are plugged in the reverb tank. Anything suggestions on where and how to start Troubleshooting this?

    If you have a multimeter, you could pull the tank and check the resistances at the jacks.....and check for broken connectors at those jacks or at the winding of the inductors. If the resistances are good there, your problems are in the circuit...bad IC???

    My first test would be to make sure the cables are plugged into the correct jacks... at both ends.

    Thanks guys, I read some other posts on this and planning to pull it out tonight and start the fixing. I have a good meter and can solder so I hope to get it up without having to buy a new tank. I will post on here what I found.
