[R-390] Little ball bearings... where from?

[John Schmitz]

I just finished rebuilding a Stewart Warner 390A which I spent a year and a
half on and I had the front panel and RF Deck completely disassembled. I'm
talking down to bare chassis with holes. I had the RF deck completely
disassembled, including planetary gear and knocking the pins out of cams to
remove them from their shafts and everything (yes, I guess I'm a fanatic).
Anyway, the only ball bearing I came across in the whole unit was a single
ball bearing that is part or the band switching and you have to disassembly
the Geneva drive to get to it. So I think I can vouch for the 390A and say
they are not from that unit. I don't know about the straight 390, haven't
taken one of them apart yet.

When my yellow striper came from Fair Radio, I found two or three little
BB-sized ball-bearings embedded in grease-turned-shellac around the RF
deck etc. The RF deck has been cleaned up and I'm pretty certain it is not
missing any of these BB's, but is it possible that these belong to a
front-panel control (for example a detent?)

The front panel and wiring harness is the next section to clean up.

Of course it's possible that the BB's date from 40 years ago (falling
out of something higher in the rack) or somehow accumulated on the
pile at SJC (which is where I would guess the RF deck grease turned
into shellac) and they have nothing at all to do with my radio.

Tim.
