Hi Burning smell from amp last night. Opened it up today and two resistors are burning up (see photo) - the 1K 2w voltage dropping resistor, and the 100K 2w bleeder resistor. Amp is a home built 6G3 lite (one channel, no vibrato). It's one thing to build an amp, but diagnosing a problem is a whole different kettle of fish. Any suggestions as to what might have caused this, or how to diagnose the problem would be greatly appreciated. Thanks in advance, Andy, London, UK.
