Seems the interstage transformer on the output of the stage (Parafeed connection) wasn't doing it's share loading the tube - or it's shorting. Then I removed the transformer connection - and measured with no load at all - very dumb - I guess my cheap VOM isn't really a "load."I replaced the transformer primary with a cap and a resistor and voila - 2.9v in and 24.9v out.
Makes sense - no load - no current flow - no current, no volts. 3 days of beating my head on my workbench....
Thanks for the suggestions guys, the breadboard on the workbench eventually told the tale.
It's gonna be a kickin' amp when it's done.
