Actually no the 805 is a standard SE output xfmer setup. I have separate filament and plate transformers, p.s. chokes, etc. that raise the iron count. There is even a keep alive low voltage 9 VDC supply with small power xfmer to activate the SS zero crossing power relays from the hum-free low voltage DC switching in the power and standby switches that share the shielded compartment with the low level audio controls. The user protection tube cage is also wired in series with this LV control at the chassis ground return end for additional safety. No cage, no go.

I do have a design under perpetual construction (too many projects) using 8 triodes (four 6080's) all in P-SET that is parafeed.

845, What beautiful chassis' you have there. If you don't mind me asking, did the chrome plate job cost a considerable sum? It's something I've always admired, akin to the Radio Craftsmen units, but never looked into the process for fear of cost and availability.

Nice job!

In the foto is the right channel.Exactly the same with the other
Now it gonna be replaced with the new one.It'll be UL p-p with a pair of 6L6GC,6SN7 as a phase splitter and 6SL7 as a driver.
But not monoblock.One chassis with one PSU.
