My model 111 was working fine .Now when i turned it on 80 tube got red fried 70 ohm wire wound resistor. What went wrong? Denver

Sound like one of your power supply filter caps shorted. When you replaced them what voltage rating did you use? Should be 450v or better.

Iused 630v. Found problem a little piece of wire was touching between 11 &10 terminals on condenser block. Where could i find a wire wound resistor?
Could i replace it with something else?
Thanks Denver

I assume you are talking about that dual (two section) resistor, 70 ohms each section, which is mounted to the chassis.
I suggest replacing the unit with two 68 ohm, 5 watt resistors. It is a bias resistor, it should not see a whole lot of current.
