I picked up a Twin Reverb in a head clone a lil while back and had it gone over by my tech, etc etc (replaced what needed to be replaced). Long story short, is that when the reverb is on, it creates a pretty crappy distortion when I play any notes or chords. Per the other forums, I cleaned the cables that go from the reverb tank to the jacks, cleaned the jacks on the chassis and tank, opened up the tank to see if there were any mechanical problems, and then replaced both V3 and V tubes. None of these changed the problem. Please also note that the RCA cables that connect the tank to the jacks on the chassis are actually inside the chassis, due to the layout of where the physical tank is (in other words, the RCA cables dont connect to the actual back of the jacks on the amp like in a Fender amp, but rather are soldered on in the inside of the amp to the jacks). Does this sound like I need a new reverb tank, or is this something more in the circuitry? BTW - It sounds really nice without the reverb on both channels. (for those that are not familiar with the amp, it is almost 100% identical to a Twin Reverb or Dual Showman Reverb). There is a schematic for this head online at the earth amp page website (something like earthamppage.com???) Thanks for the help in advance.
