I'm working on a K200B-5 and trying to fix the reverb problem. So far the pan and wires checked out good. I'm geting residual reverb spring sound from the tank by tapping on the pan but no signal from the preamps getting threw. There is somewhat of a drop in volume when the reverb control is turned up. This drop in volume is present with the pan wires connected and disconected as well. I checked the values on the transistors and they all seem to be close to the schematic values except for Q-801 has a value (I would believe on the collector) at -.13 when it should be -.9 ! I checked all the caps for shorts and replaced the transistor with a new 2N5088 and the values I get on this transistor is still -7.2//-6.3//-.13. Anyone got any Ideas where to go from here? Thanks STEVE C
