5150II problem Schematic or help needed

lastxhero · 13th May 2006

Hi all,
I have a 5150II sitting on my bench right now, stopped working so have some electronics knowledge i took it apart and found a cold solder joint and a burnt out resistor. The solder joint is now fixed, but for the life of me i can't find a schematic for the value of the resistor, and the bars are burnt off of the actual resistor.

If anyone has a schematic for the 5150II, or could give me a resistor value for R69 on the main board that would be very helpful.

P.S. i have an email in for Peavey tech support to send me a schematic. But i'd like to fix this before the weekend is over.

Thanks

Hi

A Google search found diagrams here...

******//www.blueguitar.org/schems.htm#Peavey

But I'm not sure of the difference between that and the II, but R69 is 4700 ohm on these diagrams.

wow! i looked forever and never came up with that site, thanks alot, after putting in the new 4.7K resistor, it works like a charm!! Thanks again.
