Hello,
The Heathkit SB-110A I am working on uses a .001/1kv feed through to pass high voltage into the final cage. This feed through looks like it has been over heated at one time and seems "loose" inside. I am not of a mind to trust it. I have looked at the major parts houses for another (Mouser, Newark, Digikey, RF Parts) and can't seem to find any. Ebay is not helpful either.
My thoughts are to replace the feed through with a regular ceramic feed through and put a cap from it to ground inside the cage (requires drilling). Or, I have a feed through that looks more like it belongs on a piece of test equipment that is the right diameter to fit but would also need the cap added. The problem with this is I don't know the rating for the feed through.
Any other ideas out there before I start drilling?
Thanks,
