I moved my working SS Hot Tip (Williams System 3) from my sons garage back to my place. It is now having trouble.

All GI lights work but then shut off after a minute or so. I tracked the problem down to the 6.3vac pins on the power supply board (3J3 pins 1-2) get super hot and the plastic plug softens allowing the pins to lose contact.

Those pins appear to run the GI and if I pull out all the bulbs the pins do not overheat. I thought I might have shorting bulbs but even with new bulbs the problem persists. It can't be a direct short as the pins dont get hot when no bulbs are in, but I don't see what would have changed during the move.

Any help would be appreciated!

hmmm, except we have been using the table for 2 years and it never did this before. I have not checked the temp of the connector before but the problem has not surfaced before this... bizarre

I've done some more work on it. I suspect the connector has melted slightly inside as even when I replace the contacts they don't get super hot but do lose connectivity after 60-120 seconds. wiggling the wires re-establishes connectivity. So I am going to replace the whole connector and see if that solves it.
