AKA Septar Socket
Build Ultranalog.com ColdWar with these with some Mazda 832's.
Few year's ago. Very nice amp.

Be carefull, when mounting these sockets. They are not always
perfectly flat. Thightening the screws to much is recipe for a small
disaster.

Just to scratch the surface
801A choke loaded, later on I will add an 807 as srpp leaving the choke as load
6uF paper/oil
1:2 step-up autoformer
813 SE bypass a la ultrapath; I think I will upgrade the OPT and go parafeed later.
Not pretty sure, I am considering to have PP at the output stage ... leaving room for that.
Heater will be DC (current regulated)
I think I will use svetlana 6D22S in the PSU. Got plenty of motorrun caps.
