Found a small metal disk (washer?) about 1.25 inches in diameter laying
in the bottom of the 390a.  There is a wear pattern on one side near
the outer edge, and a small hole in the middle where it is apparent on
the other side that it was fastened to something with a screw.  I can't
grok where it belongs.  Anyone have a clue?

The power supply has the solid-state rectifier mod.  SN 2327.  Saints
preserve us, it looks like all the modules in this thing may be
original.

Time to go out and play in the heat.
