i dont see a small amp tran blowing on low voltage but no fuses on the board were blown!! as i read the print this amp should see 40v the print showes 83v with coming in from power supply then thru a resistor to the amp am i reading this right

two other bands in the area had amp problems they said that someone checked the outlet and found that there was only 90v

frist of all i want to say thanks to you people that put on and maintain these forums! you people really do a wonderfull job. i am glad to see some body keeps these old schematics. i belong to several forums and never found one that i did not find help at the transistior that is blown is on the frist board print on that link i did like you said and did some creative guess work and came up with mps-6534 the people that brought me the amp said that thought it was a under-power or low voltage this is where i have problems this transistior comes off a +83 volt with a i do belive a 133 ohm resistior on the base side?

that not much better i can make out some of the componets some are just not readable is it readable to you?

have a peavey pv-8.5c that has a blown trasitor the schematic i have is not readable anyone have one thats readable
