OTL tube amp amplifier production - schematic

rallel, the impedance will be further reduced, it can be removed from the output transformer used double supply and reasonable bias position adjustment, can be removed from the output capacitor, the whole circuit is shown in Figure 1-33. The figure shows the operating voltage o RPl between levels. RP2 set maximum resistance for adjusting the final stage and screen flow midpoint output. Multimeter set 1V block were measured and down tube 5 (! Voltage across the resistor, adjust RP1, RP2 so drop across the resistor 0.2V.
