An R-390 I picked up years ago at a local Hamfest stopped powering up.
Traced the issue to the SPRAGUE AC line filter.
Replacing it w/ a CORCOM 3EQ1, which fits in the space where the original filter was installed.

I recovered the original 4-pin male R-390 power connector from the SPRAGUE filter,
so that the original power cord and appearance can be maintained.
