Hi,
You state this :
"This is the only way making a PS for a direct couple SE amplifier like the DRD. What do you think? "
1What do I think?? Ha, you asked the right guy!
"This is the ABSOLUTE POOR WAY of way making a PS for a direct couple SE amplifier like the DRD. " No good.
Thats what I think .
I don't do DRD, don't want the cap in there where it is. I can do a Rk cap better than most, so its no problem for me. I prefer a simple a circuit as possible, Loftin White amps hold my interest the most. I prefer conservative tube dissipations and want ultra reliability to my builds.
I used to always regulate B+, no more. I like dual rectifier tubes and well-designed "modern" L1/C1/L2/C2 filters to the Finals.
A 2A3 DC amp needs 480 to 490 VDC of B+. A 6AQ5 DC amp (lower power) needs about 430 VDC. As for power supplies, email me privately with your own email address, and I will send you a couple of great papers as attachments, on what we are doing now a days, which is quite different from what you are thinking. Address above. Read them over, then ask questions !
Cheers,
Jeff Medwin
