Re: JCM 800 #2210
Hi Gil: If you're talking about the JCM 800 50 watt master volume amp, there are at least two versions of this amp. I owned an '82 and an '86 and had a chance to compare them. The '86 doesn't sound as good, and divides the voltage to the preamp tubes differantly. The '82 uses a dropping resistor for each tube while the '86 uses a dropping resistor for the phase invertor and a single dropping resistor for the remaining two tubes. There's other diff's too, but it's been a while since I owned the '86. I still have the '82 - great amp! Lew
