Hi All,
I was hoping to be able to short cut learning how to design a power supply suitable for the amplifier I wanted to put together and ordered one of these: PS-Tube-SS Kit for Tube Amplifiers Schematic is embedded on that page.
My greatest hope was that the manual for the PS, together with the kit would allow me to build my own power supply for this: Tokyo Metropolitan Life, Tube Audio and ROVER 75 (google will auto translate if the link is opened in Chrome I believe)
But I was pretty disappointed when I received the PS kit and upon reading the manual there was no formula for spec'ing a suitable power transformer.
Can anyone please tell me what voltage transformer I would need to achieve the 207V(or 214V) B+ in the linked 6EM7 schematic?
Would an Antek 5V transformer of suitable VA be suitable? I could use the 5V to rectify for 13EM7 heaters. But then use the second 120VAC winding for B+. Would that work? I know that Mr. Broskie provided for tuning final voltages via resistors but I don't know much more than that.
Any help greatly appreciated.
Erik
