WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
Tube data indicates the tube is used for a tv vertical deflection amplifier. Can each section be used as a line level stage with similar results as the 12b4 which is also used as a tv vertical deflection amplifier. If so what would the plate and cathode resistor values be.
This tube is similar to the 12AU7A/ECC82 - take a look at typical operating conditions for that tube..(Any RCA tube manual) Much higher mu (20) and rp than the 12B4 incidentally. I used them extensively as long tailed pairs in some of my early commercial PP designs.
