I converted the Bogen to cathode bias and the voltages came up a little higher than predicted but once I have the preamp and PI wired up they should fall right back in line. Cathode voltage? Spot on at 18V. The 7591 plates are at 480V and the screens are at 430V (w.r.t ground, not the cathode.) Even with the preamp tubes in I'll probably have to tweak the power supply's dropping resistors slightly because DAAAMN.
Dead silent so far - as damn well it should be! We'll see how that holds up as I get the preamp and controls wired up, but man am I excited.
