[R-390] Restoring my '390

[Jim]

Brian,
I'm just a hacker with this stuff.  My degrees are not in engineering and I 
have never worked in the electronics field, BUT, I've sure blown up and let 
the smoke out of a lot of radios.....
I like Collins and started fixing them before the internet and before I 
could afford the "proper" test equipment.

The stuff is idiot (me) proof....just follow the directions.....
There are some screwy problems and the list is here........

Slightly OT....
To this day I can't tell the difference between a 75S-3B aligned with the 
Xtal calibrator and a good signal generator........


73,
Jim
