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

[Tim Shoppa]

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.
