Hi
The reverb of this amp is not working. I checked the DC resistance of the input and output coils. The output coil reads approx 220 ohms, but the input coil reads only 0.9 ohms. Does this mean that the input coil has shorted. Please assist.
Thanks

That may be normal; this is a low-Z tank, and the DC resistance is much lower than the audio resistance.
Leave the output coil connected to the amp. Get a 1.5V battery. Strip a RCA cord. Jumper it all so you can tap the 1.5V onto the input coil. It should BOIINK! loudly.
Use that RCA cord to connect a loudspeaker to the reverb driver. Disconnect the main speaker. All knobs at normal playing position. Does the speaker on the reverb driver make sound?
