6.3V should have rang the bell .... It's indirect heated , so forget about
my argument !!
So it's a heater supply , not a fiament supply !!!

I would use a 12.6V 0.9A and take the CT between the tubes , not on the
tranny .
Gives a cleaner sound since the trash from the mains get less chance

Hello RATS!
I am looking for a low DCR power transformer for filament supply of
rectifier tube because some one told me that the low DCR power
transformer the better regulation it is.

I would say that regulation is a non-issue here. The load is constant so
regulation doesn't matter.

I want to use the 6D22S rectifier tube (2 for full wave
rectification). Therefore, the power transformer for the filament of
this tube is going to be 6.3V 4A, will it be ok?

Yes, probably. What you need is a transformer that will supply the tubes
with 6.3V with a 1.8A load. It doesn't really matter if the transformer
has a 2A or 200A rating as long as the voltage is correct at 1.8A.

I would get a 3 or 4A transformer.
