Which Schottkys have a high enough voltage rating?
C3D04060A 4A 600V Z-Rec SiC Schottky TO-220-2 | Wolfspeed
with 390V in B+ rail.
10+ years ago, maybe.Is this true ?
Schottky diodes are the way to go unless you need to have a rectifier tube to look at.

With Schottky Diodes , he did not have a good outcome.
I thought they were the best option, even with a 0.01uf 100ohms network, through the diodes
You could do the experiment yourself. These are very inexpensive parts.With Schottky Diodes , he did not have a good outcome.
there are not other same amp.
Is a hobby , and i am building this with 6c45P , 45 , 300B , with coupling and OPT Lundahls transformers.

What would the #45 do that the 6C45 won't?
I dont know but Susumu Sakuma used coupling and output transformers ( not cap ) and DHT to drive other DHT.
If not have a good result , will go for 6c45p with Interstage Lundahl 1:1 or 2:1, and the 300B only.
More conventional aproach.

Yes, Sakuma would put a step-up transformer in front of the #45 and a step-up interstage between the #45 and 300B, then he'd throw the 6C45 into a drawer.
Personally I would rather have the 6C45 driving the 300B. The 6C45 is more capable of driving a 300B than a #45 is.

the 45 is there , only because of a whim.
Probably, surely , will end up working only with the 6c45p 1:2 Lundahl transformer coupling and the 300B
I dont know
You really need more gain? The 1:2 step-up seems like a waste. A 1:2 step-down might not be that out of the question.
Do you thing if not use the 45 between 6c45p and 300B is enough gain ?
Only 6c45p and coupling transformer 1:1 or 1:2 and 300B ?
