Illuminati (2nd Degree)

Hey-Hey!!!,
It is indeed 750 Ohms. Since I don't need much gain, or output swing, I used a low plate load. Remember that for transconductance devices like pentodes the stage gain is ~gm*Plate-load.

The g2 voltage is 75V, and gm is published for that OP. The bias is ~5.5V established with a 100R cathode resistor. Actual plate V is about 150 as dropped from a B+ of ~200. I may even try a lower value plate load...:)
cheers,
Douglas
