5150 combo tubes
take the back off an lay it down on it's face and come
around so the controls are closest to you(so the tubes are pointing up)
(and I know we're looking at this the same way from the same angle)
the first tube on the left is V1. they go left to right.
you've got 5 pre amp tubes V1-V4 are for the channels and the reverb (v4)
v5 is the phase inverter and is the on furthest to the right (closest to the power tubes).
V1 has the most effect overall on tone I have tung sols in V1,V2, and JJ's the rest of the way.
Put a balanced tube in v5 (phase inverter) for best results.
and lose those crappy stock power tubes. your ears will thank you
Now get metal
