HELP NEEDED CTC203 RCA
Looking for information pertaining to the following components of an RCA
CTC203 chassis. R14107 resistor - what is the value? Q14101 FET - what is the part number, etc. Possible for a schematic diagram??? Hope I'm not asking for too much. I'm stuck now after finding the Horizontal Output transistor shorted and a few other smaller resistors,open, I accidentally blew up the FET. Any help would be much appreciated Dan |
