Curt,
Does not surprise me...is it a supply that has had a full update
(Heathkit shop or other)??
If not I would do that right now. Everything in there is getting old.
73,
Lee

Subject: [Drakelist] AC-4R Surprise
My T-4X quit working today, the 250V supply was gone. Filament, bias,
and 650V
supply normal. On investigating the AC-4R board in the AC-4, found two
parallel
5W 200ohm metal oxide resistors in the 250V supply circuit OPEN.
Suspected a
shorted capacitor, but the cap is not shorted. Anyone else experience
similar
behavior? 73 Curt KB5JO
