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.
Some years ago I bought box of 1R Mills MRA12, so I used its instead of 0.82R, which was in the kit.
V7 was capable working at 90% potentiometer value with 1.25A.
Work in progress Vin R. C. 25VDC, same PSU as 26 C-L-CMC-C, PSU needs resistors to lower the Vout to 24VDC or maybe 23VDC because the attached pic is the max. attenuatio can gives the trimmer. First to try the valve I used a 50W 6R8 power resistor.
