I bought a TR-4CW/RIT off ebay and it would jump in frequency even
when just listening. I found that one of those dumbell ceramic
capacitors inside the PTO
had a very small crack in it. I replaced the cap and all is well.

Hi People,
I've got an R4C that is jumping frequency by +- 1 Khz, then
slowly returns to the correct frequency only to repeat again, and again.
I have installed the ground strap mod, and exchanged several
tubes, cleaned the switching, and checked all the RCA jacks on the
rear panel. At this time I don't know where else to go. Has anyone
had/ corrected this problem? Any help, or suggestions would be
greatly appreciated.
Tom
