Here is my home grown from a ultra-linear push pull amp from a design of a
6P41S, 6N5P,6N1P.

The meter is on the plates of the output tubes.
The B+ is 315 VDC
At full output the plate ma is 80ma for both tubes.
I am using fixed bias with a 500 ohm 25 watt resistor
The bias on the control grids is -47 VDC.
with a by-pass cap of 47 mfd. 250 VDC.

I got everything from a e-bay search.

Here is the basic schematic (This schematic does not work!!! I had to tweak it to get it to work.)

How do you find the 6P41S? What is the B+? VU meter too, looks good.

Edit: or maybe its a B+ or mains meter?
