Re: help on finding a subsitute for a blown feedthru cap please


 

Jim:

Answered this one yesterday....guess you didn't see it.

The four feedthroughs in your pic are all .001 uf? @? 350VDC.? K4OAH's Service Manuals tell us this kind of info and are highly recommended.? Available at K4OAH.com from Garery's wife.? Sadly we lost him in 2018.

However...the hole to the right of those four feedthroughs is missing the?+650 VDC lead which passes through a small piece of plastic tubing that should be in that hole.? I believe the original was a short piece of bare wire with a tiny loop at each end which helped to hold the insulator in place in that hole.? The insulator needs to be capable of handling the high voltage that?runs to the anodes of the 6JB6 finals.? I don't see the wire from the C-J connector on the back of the radio, but perhaps it is out of the picture?? FWIW, the original insulator was black in color, should originality be of concern.
