I need some help with a tube amp ... so... i have built a weber inspired smokin joe 2 tube amp. i want to mention that i did not use a kit...i scavnaged the parts from here and there..it worked as a charm from the first volts he sucked in... i tested it.... for an hour or so..anyway...the next day...i plugged it in and noticed that it sounded really poor-- tone and volume loss without limits...and the day before i almost got kicked out of the building by my neighbours... i redesigned it...measured all the caps the resistors...they seemed to be fine...i used new one... just to make shure...still the same...the only thing that i did not change are the powercaps
