I have a tram d201 vox model. It has no modulation. This is the one I posted about here last year that was sitting and receiving and suddenly burned the resistors and disc capacitor at the audio 6l6 tube. I replaced the burned parts and replaced the main power supply capacitors. But it has no modulation. and the power level is down to about half of what it was before the problem occurred. Before the resistors burned it had a carrier of 4 watts and modulated upto about 12 watts. Now the carrier is around 2 watts and no modulation. It actually backs up about a 1/4 watt on modulation. I think maybe the capacitor that burned was actually part of the compression/gain control. Can someone maybe try to explain how this audio gain/ compression works or relate any ideas or experiences as to what the problem might be?
thanks in advance for your help.
