[R-390] 390A knobs

[Paul Galpin]

Hi all!

Progress is proceeding, and one of my 390s works just fine. the other lacks
a 17M/200k crystal unit, but looks complete otherwise.
I/m concentrating on the cosmetics first, to have a nice clean worker, while
I work on the non-worker!

I have a large selection of 390 knobs, now all re-painted and white-lined,
and I find that I don't actually know for sure where they go!
the big knobs are for the Mc/s and kc/s, that's a no-brainer, but the
others? I looked in the Y2K ver3a parts list and find that four types are
called for.

1  8x B 249242-1
2. 3x B 249242-2
3. 3x B 249242-3
4. 1x B 249243 (Knob, tuning)

Only one tuning knob? If it can be that wrong on one knob type, is it right
on the others?
since No1 has the greatest quantity, I guess that's the small ones, but what
are the two other types? Medium white-lined and Medium all-black? But Fig
6-37 only shows 2 all-black (zero adj and dial lock)
And which knobs go where? The Y2K is singularly unhelpful on this. Fig 6-37
has all the knobs the same size, except the two tuning knobs.

Apologies if this has all been logged to death before!
