I have exactly the same experience as LUO, I have no succses of the
filter Cap's holding up the 1.414. My sag is very near 1.414 becomes 1:1
I belive the solution is to use a choke to drop the peak volt at no
load,
so it then will be possible to raise the secondary voltage from Xformer
without risking to hit the anod voltage limit of the tube in question.
Sure know Henry 4k Ultra use a choke and seems to be a smart way to go.
Now the question: How can I use a choke if I have a voltage doubbler??
Can I put the choke in the B- side of a voltage doubbler ??
