Good point, the ball in the Geneva coupler is there and working
fine. It did get dropped on the floor at least once when I was
rebuilding the geartrain, but it's back where it's supposed to be!

In fact a quick look-see confirms that bandwidth detent in the IF
deck has its ball too. So who knows where those little balls came
from, maybe I can put them on Ebay under the 
heading "Art Collins' lost balls".

Right now the subject of swearing and consternation is that while I
was putting the chassis back together, several of the original 6-32
machine screws had their heads simply snap off. (And I'm not exactly
putting this thing back together with an impact wrench!) One of
them was at least a little my fault (too long a screw) but a lot of them have
a lot of corrosion right under the head.  Time to
abandon the old corroded hardware I guess, and get a left-handed drill
to remove the #$!%#%$ broken screws.

I did fix up the broken fuseholders on the back, added an IEC socket
and filter, an inrush current limiter, etc., and am happy with that
progress. Strangely enough the B+ fuse that has 4 wires to one terminal
(F105) had never had one of its terminals soldered, I don't think it
was a recent replacement because none of the wires nor the terminal show
any sign of solder! Still have to replace the very banged-up-and-rusty
selenium rectifier (almost certainly with a solid-state bridge, I think
Barry was doing this too, how did that turn out BTW?) and the screw
terminal strips on the back are missing some hardware too.
