Default 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
