[QUOTE="Metallifornia, post: 76091, member: 2614"] 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 driver op-amp they are the same 4558 op-amp. My RH50 head started to sound like the gain would trail off after a couple seconds of sustain on a chord. The switch contacts were going bad. I still occasionally have to give it a jiggle to get it to full operation. For the 6l6 setup (which I think sounds better) just short R147 and adjust bias to your taste within 50W limit of the output transformer. I have been playing mine with 6l6's for 2 years with no problems. Are you running a 12AT7 for the phase inverter? -Brian [/QUOTE]
