Cathode resistor on outputs looks far too low to me

DougL · 24th December 2008, 05:55 PM

I ran the output stage through Tube Cad PP Calculator.

Current per tube 95 mA
Plate Dissipation 27 W / 67% max

22V across the cathode resistor. 191 mA, 4.36 Watts, recommended bypass 332 uF.

Looks OK to me.
