Hello everyone, I'm looking for a .39 ohm 5 Watt non inductive dual emitter resistor. I've checked all over the place including Ebay, and have come up empty handed. MCM used to carry them, but appears they no longer have them as well. Just curious if anyone here might have a source. Thanks.
You will find even wire wound resistors are quite low inductance as they are counter wound to cancel out inductance.
Some single resistors are non-inductively wound.
Yank the dead part and use a pair of new resistors. You could move to a 0R33 resistor if that's easier for you. Just modify the voltage drop value in the setup instructions to give a voltage drop for the new resistance. This will also affect the over current protection, but hopefully not enough to worry about.
Why yank the dead part? Because there isn't room to neatly mount the old part with the new ones. They do make vertical 5W non-inductive resistors that should fit nicely, but I'm afraid those nice "plate" resistors are long gone.

Thanks for the response.
It was some advice I received from you awhile back, making me hesitate to use anything other than the original type. Here's something I just threw together which might workout OK. It uses standard 5 W axial resistors while retaining some of the original 3 lead look.
