In Reply to: RE: HK Citation 2 rebuild questions posted by Jim McShane on April 13, 2015 at 05:19:51
Hi Jim, and thank you for the suggestions. Re. changing the caps, ok, I actually was thinking of putting in some 100uf x 450 caps initially, and thought that it was too much.
Now about the bias supply, what is it that 1.8k resistor doing? If I don't want to completely supplant the bias supply, I should just rebuild it as stock? regards, Dak

As I mentioned before there is an issue with the bias winding in the power trafo. No amount of rebuilding the existing circuit will save you if the winding fails. That's about all I can say without being in violation of the rules.

Well, can you speak about the bias supply requirements? Surely, no rules violations there. thanks, Dak
Dude,
Pay the man his money! Buy a bias PSU kit. Jim has gone to GREAT pains to develop a replacement bias PSU that works very well and fits in the limited available space.
As Mr. Hegeman is no longer with us, keep in mind that Mr. McShane is the living expert on tubed H/K Citation equipment.
