Fellow Keepers,
Acquired a nice Heathkit TT-1 valve tester today in fair shape.
The worst part is that the Grid current test switch is trashed.
Part number 63-223. Someone soldered the contacts and someone else
turned the knob, result, broken wafers. Maybe should order the switch
repair stuff from Mouser. Or perhaps rebuild if I can find some 1-80
Anyone out there got one??? 73.
