This CTC131 was hit by a major power company surge. It belongs to my buddy or else I'd say to forget it. Anyways, the chopper output Q101 and chopper shut off Q100 are both shorted. R103 47 Ohm is open as well as R106 2.2 ohm. Does anyone have the RCA part numbers for the transistors, and also workable subs if any? Thanks for any help. -- Gary McCartney McCartney Electronics Guelph Ontario Canada Est. 1984 email: gary (at) number63.ca ----------------------------------------------------------------------------- Lost Password: http://www.tech-assist.org and select "Login Problems?".
