Looking good Ray, much shoddiness as usual.

I've been busy again today, all the power supplies have now been hooked up and tested and I'ce got the grounding ready to go.
Power supply is CLCLC (pretty obvious!) for the 13E1s and a Maida regulator running at 350V for the Aikido input/driver stage. Three switches on the rear panel to sequence the power up.

Cheers.
1. Filament supplies
2. 6SN7 supply (Maida Reg)
3. 13E1 supplies
I could have just used two switches (filaments & B+) but wanted to have the little bit of flexibility when testing.

Very nice, Ray. Your patience pays off.
But it looks like you won't use Maida reg. for the 13E1 tubes. Why?

Very mysterious answer...Patience is a virtue Wolfgang...
...and I am working on something in order to overcome the dynamic limitations of 1-2W SE OTLs with the help of Maid reg.
