Hello folks. I have a little amp that I can not find much info on. Problem is on the power setting switch. 2 of the padding resistors are burnt/discolored and I don't trust the values my meter is reading. Nothing on CB tricks that I have found. Been burning thru the Google searches for a week and down to my last tuff of hair on my head!

Amp board just says Model 150 and PCP inside a circle? Uses 2 Motorola SRF2072 transistors. Any info will be greatly appreciated especially a schematic. Other wise I may have shoot in the dark on the values. Thank you.

Gotta be real old school there. At first glance of the title I thought you had a Cobra 150 radio.
 
LOL Driver. No, I hear some horror stories on the 150 and 200 GTL radios. And I have plenty of radios that work better for me. This is a strange little bugger for sure. Looks well put together inside. Everything "appears factory stock". Me thinks someone may have tried to drive it too hard at some time.

Neat looking old amp. There are several sharp tech members here, I'm sure one or more will chime in and help you.
