RE: Schematic shows
Posted by PeterI on June 14, 2017 at 07:28:48:
Yes, it's dialed in now. The schematic showed -45V at the bias source AND -45V at the grid which must be wrong, after passing thru resistors.
Now have 396V on plates, about -32 to -33 on grid, and 1.17V at both OP tube cathodes. Sounds better than ever (naturally). Around 42-44mA. Will do more minor tweaking. And gotta drop filament V down from 6.6V AC.All tubes made 1950s.
Thanks for input.
