Temat: dziwny (dla mnie) inverter...
...since the signal is on the
cathode rather than the grid). This makes the current swing in the driven
half 20% larger. Since the current through the tube sections is relatively
a function of the input and independent of the plate resistors, the plate
resistor values are adjusted so the the voltage swing in each section is
the same.
The unbalanced output effect of a phase inverter is greater with a small
cathode feedback resistor, which the Bassman's 10k ohm is. Some Vox amps
have a large 47k ohm cathode feedback resistor. The cathode feedback is
high enough to neglect the unbalance, so the plate resistors are
equal (100k). In fact one input drives one side of the inverter, the other
input drives the other. The high amount of cathode feedback does limit the
voltage gain available in the inverter.
