Yes...the flyback is a possible problem on these sets, but it seems like the flybacks got better by the time RCA got to these sets...have not noticed as many cases of flyback failure on the 38's/39's as on the CTC-31's and CTC-16's.
To diagnose where the short is, I start at the end of the filter capacitor/resistor chain, farthest away from the rectifiers, and disconnect one branch at a time, and then observe the short checker lamp to see if a short is still present. If so, I continue disconnecting further back the chain till the lamp goes dim. If you get all the way back to the diodes and the lamp is still bright, its likely shorted diodes.
