Hi,
New here, although I've admired these amps for a while. I managed to score a few NOS 6A3 recently & so planning a GSG build.
Received the PCB from Shannon & have been accumulating the other parts & just received a pair of James JS-6113 output transformers.
The last items are the case & power transformer.
I'm in a 230V area & have a very nice power transformer from another project which has dual 6.3V 5A taps. The main HT secondary is adjustable from 250V to 400V in 50V steps. So I guess it should be wired for 350V in the GSG - would I need to adjust any of the PSU component values (R17 & R18 particularly) to achieve the required 300V output, or since it's within 10% would it be ok. I have the specified Triad choke.
Thanks for any advice.
Chris
