K2/K3 Proset

[John_N1JM]

I bought a K2 Proset some time ago that was converted to an HC-5 element. I have the
original iC element. My question is , is there a series resistor
involved with pin 1 or is that kind of built into the K3 when I turn
bias on? I'm thinking of converting it back to the original. I have
the mic adapter but there is no resistor in that.

John,

The resistor is in the K3, not the headphone.
