Hello

I would like to ask for some help, advise.
I received the GM70 tubes and I have all the drivers sockets etc.
Now I start looking for chokes, transformers.
My question can I use these transformer for the driver stage (400V) and for the bias set up to(200V) with out degrading the sound of the amp.

May be I can save some money if I need one transformer less. Any way it cost a fortune all the transformers chokes. Or it would be a short cut which not the best idea?
If yes please advise how I can reduce the voltage to get 200V.
Thank you very much.
I attached the schematic after I build my GM70.
Greetings gabor
