Go for the Effects loop level switch on the back (sw4) it switches in 1/2 of IC3 (a 4558 op-amp). The first 1/2 is a buffer which is always running and the second half is an voltage amplifier which gets switched in to help compensate for long cable runs. You could swap IC3 with IC2 the reverb...

I just noticed you said 6L6 in your RG50TC. Did you modify the bias circuit to give a wider voltage sweep on the grids?? That could be the source of the low volume. The great thing about these amps is that they have external bias pots, testpoints and 1 Ohm cathode resistors. Just be sure to...

Start by plugging into both of the inputs to see if there is signal passing both inputs. The difference between high and low inputs is 68Kohm (low) or 32Kohm (high) input impedance. I have had amps across my bench in the past where guys have burned up the input resistors by trying to plug in...
