DCR of plate choke

Posted by Tubenstein on March 8, 2017 at 21:34:12:

Hello!
Let's say I want to replace the plate load resistor with plate choke. Assume the plate resistor is 1.96K, should I have the DCR of the plate choke make for 1.96K?

Someone told me that a reactor is not same as resistor. A plate choke is a different impedance (reactance) at each frequency, increasing its value as frequency goes up.

Example:
A plate choke (reactor) to be 1960 ohms at 25hz, needs a 12.4H choke.
................................................at 1khz needs a .311H choke
................................................at 10khz needs a .03H choke.

Is that true??
