Pulled a high speed vacuum relay, Jennings RJ1A, out the other day
that I was saving for a QSK mod to my old amp. There is component
across the windings of this relay that I can not identify. It is
soldered, or silver soldered, to the winding terminals. It is about
3/16 square, yellow, and has the following markings: JAVX 8652 AA M390
14/01 1553.

Here is a slightly out of focus picture.
