Bah! Controversial or no, if it works, it works. I would like to
get together a solid state regulator for the 390's. I have a couple
decent circuits that I'll try when I run low enough on 6082's.

Now a new project -- 63 Imperial 390A #1 now has a 17 MC oscillator
that isn't. It's not the tube and it's not the crystal -- but it
*did* happen less than a day after buttoning it all up from an
unrelated matter.
On the plus side, while I had it out I was able to get my PTO end
point setting to w/i 100 hz, and linear across it's range.
So... lessee, 63 Imperial 390A #2 (from the SK lot) had a slipped
clamp so I need to resynch the bandswitch, though I may be able to do
so w/o pulling the deck.
51 Collins 390 #1 & #2 both are full of bugs, the electrical kind.
but '67 390A EAC works, so I'm not totally 390A-less.
There's the WRR-2 and the T-368 in the living room, where they may
stay for the next few months, as well as a barn-worn SP-600 vanilla
that I've not checked at all. (Think I fussed about that last week)
There are probably things I've forgotten about and should be doing,
like working on the house...

I'd rather roll around in ground glass and razor blades than replace
the caps underneath the RF deck of a Super Pro. Bleh. FUN!
Like Cecil says, the idea is to have fun. All but the #1 Imperial
and the '67 EAC are projects from *last* winter. Last winter I spent
working on projects for a couple other folks, as did I this summer.
Argh!
