A Thankyou to the responders of "Variable B+" from Dec. I am like a parent that drove off and left his kids at WalMart.     Just before Xmas break I posted a question seeking Variable B+ supply schematics.     Eight or ten people responded and I never thanked them.     I kept meaning to, but...     Anyways, thanks for your thoughts and time.     I have reconciled myself to the variably biased grid on a 6550 as a triode pass element, rather than any variac option. The down side is I have to reset bias with any change of voltage point, so it won't be done on the fly, such as when the band gets louder, latter.     I have the xfmrs, sockets, pots and jacks in the chassis, now. I expect to wire it over the next month and start prototyping regulators. I'm hoping to get away without a gain tube to magnify the error signal sent to the grid of the pass tube, as was shown in one of the posts.     I'll report when I have something useful to say.     Thanks again, guys. Sorry to be such a Dork.     Dan
