Does anyone have the specs for the voltage going into the Anode Triode on a 5150? On the Mesa's and Soldano's its very high voltage.
my 5150 script logo measures as follows (give or take 10-15 DCvolts depending on whats running in the house, so take it with a +/- 20 or so!)
plate volts at pin 3 of power tube - 495 (i've seen it as high as 515 though)
preamp main tone tubes at the plates measure DC volts as follows:
v1a (first gain stage) 160dc
v1b (second gain stage) 217
v2a -295
v2b - 168
v5a - 248
v5b - 189
i assume you dont need the fx loop or PI tube readings as there wouldnt be any real way to implement these in the ada mp1 mod.
v3 is the effects loop tube
v4 is the phase inverter
