When I found PSU simulator from Duncan's, I shouted with joy!
But I see some weird things happen now. See the picture attached please.
I set 100ma for output tube stage, and 6ma for driver tube from 330V (RMS) transformer. I added 4k5 in order to drop voltage for driver stage. Oh, I am talking about a pentode SE amp.
Well, according to my manual calculation, voltage in c2 should be around 250V, because 27V drops from the previous one by 6maX4.5k)
But the result says 190V. Wow, I cannot understand this result. Moreover, when I measured a REAL amp with my tester, I found that my calculation was right and PSU II was wrong.
I tried to contact Duncan for this matter, no reply has been made. Anybody can explain this? What did I miss?
