[Boatanchors] [Hammarlund] HQ-150 Line Bypass Caps Needed

[Carl]

The Vishay WYO caps I mentioned earlier are both X1 and Y2 in one package 
rated 440V in X1 and 250V in Y2. Certainly fine for a lifetime at 125V.

Ive never had a need to deal with a garage operation for basic caps and find 
Mouser far superior in pricing, availability, telephone service and fast 
shipping.

Many of the BA's I get in here for overhaul have blown AC line caps of the 
waxed and molded paper variety. I dont recollect any bad disc ceramics, at 
least those that are factory installed.
