Wonder if anyone could give me a little help? I'm restoring an Atwater Kent 55C and found a shorted 1st AF Bias Resistor. These resistors are wire wound and this one is 1050 ohms. Can I replace this with a regular 1 watt resistor or did the engineers who spec'd the wire wound resistor want to produce a reactive load and hence required a wire wound resistor? Does the inductance of this type of bias resistor help stabalize the AF?

Thanks!

Hi Lee

This is a cathode resistor, value 50K ohms. You can use a regular 1 watt carbon resistor.

Before changing the resistor check the cap in parallel with it. The cap may be leaky? It's unusual for a resistor like this to go down in value.
