Mission Accomplished!
All the parts arrived while I was away on vacation, spent the weekend doing the job.
Did the power supply w/ 100 - 50 - 50 - 30 - 30 all 500v F&T
Upgraded all the 25 uf caps
Changed the caps in the tremolo
Rebuilt Baxandall w discreet components
Rewired the 7199 for 6U8A
Cleaned chassis and cabinet
Deox pots and sockets
Built a dolly, thanks to Bruce @ FlipTops for the Dolly Knob assembly

W/o a polarity switch I did leave the power cord as is. Depending how amp is plugged in it will run a bit quieter. So I put in a new film death cap. I'm not terribly concerned... A lot of the time I use a ground lifting plug on gear to minimize ground loops, so that negates a grounded plug anyway. Have a cord ready to go if I want to add in the future.
Brought it back to life on a variac and all was calm and uneventful. After watching the amperage draw for a while, played some chords and all was good. Good tone, and volume, reverb and tremolo work and original AlNiCo Jensen sound fine.
All the original tubes are tested strong and are being used, except the 7199. I got a pair of novar/magnoval socket adapters. When the outputs do wear out I can then use EH 7868's w/o worrying about the sockets. I use the adapters in my Fisher 400 and my Gemini II.

Jim McShane is a good tube source and he will even sort out a pair of 7868's that run "cold".
