I? made a serious? error? when plugging numbers into the PSUD-2? ?power supply software.? Like an idiot,? I used the? wrong? plate xfmr? ?DC? primary? resistance.? I was plugging in? ".1 ohm"..... when it shoulda
been? ",01 ohm" .? ? ?Well that? makes a helluva? difference? to the calculated? ?source? Z? of the? plate? xfmr.??
I did have the? secondary? ?DC? resistance correct though? ( 4.5 ohms? across the 3900? tap....and? 6 ohms across the? 5200? tap).?
On the 3900 tap, source? Z? is actually? just 7.411? ohms.....? and? NOT? ?33.61? ohms.? ??
On the? 5200? tap,? source Z? ?is actually just 11.61? ohms.... and NOT? ? 57.6? ohms.?
B+? ?V drops? under a steady...or? varying load are of course? much improved.? ?Hardly any drop at all.?
The resonant choke? setup is still? a dud? though.? ?It's? a glorified? 120 hz? notch? filter...and let's all the? harmonics? pass on through.? ??
Too? easy to make? errors.?
