JohanRe: Differences, Marshall 2204 jmp mv and jcm 800?
over the years I've owned both JMP and jcm800 version of 2204. the JMP's had two 10k/2W resistors in the HT supply between powertubes and P.I. the JCM-800's has had only one. the resulting voltages in my amps was roughly 270volts on the cathodefolower( eq-drive )in JMP and 330volt on the JCM-800's, giving more preampdistortion in the JMP's...
