Power Frequency Ripple Reduction in B+ Supplies
"Patrick Turner"
** FFS - just add 2 ohms to the 38 ohm winding.
Problem gone.
Dodgy 5U4s etc not withstanding.
SET amp loonies sure are a bunch of neurotic old women.
I'm not so sure an added 2r to a winding with 38r would fix the "problem".
** Who cares about that.
What if there is slight difference in turns of the CT winding?
** Not at all common and not mentioned in the OP.
What if there is Idc imbalance in the two output tubes?
** Huh ??
Got nothing to do with the issue of 50Hz PSU ripple.
