Help! Restoring a Collins 32V-3, and the RF loading Capacitors, C-411 and C-412 (470pf) Caps are bad. Type H Sangamo Mica 2500WVDC. These caps are in series, and sandwiched in the RF output network. They extremely hard to get at. It seems that only a close replacement type will fit, since there is no other room in there to improvise. Any value between 400 -500 should work as long as they have ear connectors on each side.
If you want to sell them, please contact me at
