JCM800 50 watt 1993 2x12 combo: Which preamp socket does what?

thefyn · 11-04-2009, 06:18 PM

Facing the back of the amp, left to right of the 3 pres , which is the phase inverter? I got a ballanced preamp tube for that slot and I dont know which side v3 is on (L or R when facing it from behind)

With the combo being an upside down head, adding to my confusion.

It'll be the one closest to the power tubes.
