My reverb stopped working, what could be the problem?

This is usually caused by one of three things: The reverb tube, the reverb pan, or the wires that connect the pan to the amplifier chassis. First make sure the wires are properly connected to the chassis and the reverb pan. Next, you can try replacing the reverb tube. Please refer to the owner’s manual for the location of this tube. Finally you may try removing the reverb pan from the black bag at the bottom of the amplifier. Check inside of pan to see if there is a broken wire from the RCA jack to the small transducer by the springs. If none of this solves the problem and you’re handy with an ohmmeter, you may check for readings across the two jacks with no wires connected to the pan. You should read about 2 ohms across the input jack and about 200 ohms across the output jack. If there is no reading, that transducer is open and the pan must be replaced.
