Hello folks,
On my Mark III stereo build, I'm using and Antek 400v 200 ma toroid, SDS cap boards and Poseidon driver boards. When I look at the connections, Poseidon wants 330v (J) and 430v (K).
Using the Duncan Amps PS Designer, I run the values (both stock and SDS), and the voltages at all B+ points on the four filter caps are way too high (SDS), or way too low except for first stage plate voltage (Stock).
Question: Does it make any sense to use a big dropping resistor on the AC or DC side of the 5AR4/GZ34? And, secondly, to adjust the voltages at the other test points can a resistor be placed in series before or after a choke?
Using PS designer, I was able to work the voltages perfectly, but not without a supplemental resistance in series with the 1.5H 55ohm choke.
Ideas and help would be appreciated on the concepts. Thereafter, I'll try to run the values again and let you know what I find.
Thanks as always,
Chris
