1965 for that set. I have the same set. You can jump the 2 leads on the thermistor for testing purposes but should be replaced some time soon. It is not on the B+ bus, it is on one leg of the AC line. Congrats, those are good and reliable sets.

It is in the B+ line and the X is later, 66-67.

The VDR is in series with the degausing coil and is there because it has a sharp cutoff. It almost totally removes the current from degausing coil because the voltage never drops to zero across the thermistor. Otherwise you would see weird color bars and noise. Think of it like a relay that disconnects the degusing coil when the thermistor gets hot.

If you fire it up just make sure you keep feeling the electrolytic cans, if one starts getting hot, pull the plug and let it cool off. They like to leak in these rcas but they do reform and wake up.

i thought roundies were done by 67 but oh well maybe this was the last made who knows. so ill have to find the vdr for the degauss being its there so i might just as well use it but the old one was burned really bad. its a model GG637 W.

They made roundies into the early 70s. They were cheap buget sets by then. Yesteryears crap.

How's the fly look and smell. These have a rep for eating flys and the direct replacements are hard to find. You can sub a bunch of stuff in there though. You have a used one right?
