Hi Jim, now that you open the bottle and let the genie out it is only fair that you detail how to implement a separate bias supply for the citation 2. thank you, Dak

Not to speak for Jim, but you might be cornering him into an awkward situation here regarding the forum's rules on commercial activity. If the mods he does are proprietary (and I don't know that they are), his only response can be to refer you to his commercial services. Really, it's not difficult to design a supply like this if you work backwards from the DC bias voltage. I'm sure any number of members can do that for you.

Well, before I found the Sam's fotofact I did not know what I had to shoot for. Now, it is just a matter of verifying if those numbers are correct. thanks, Dak
A radio shack 25.2v/450 mA trans on a doubler should do it. 50 and 100 uF Nichicon Muse should do...and if Jim kicks in that ~65V of negative is not enough, pick a 30-ish volt Hammond that will fit underneath like the OE choke.
cheers,
Douglas
Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
I saw a Sam's fotofact that shows the bias supply requirements at 2ma current and -55v . Is this correct? Sam's can be notoriously wrong about certain values.
Why don't you just measure it?
