Thanks for the ideas guys. Nick, being new to this kind of thing, I'm wondering if wattage matters here? The petronix fix suggests 1/2 watt, that one is 3 watt, does that matter?

The resistor is going to be plan B now. Don has received a 'filtering harness' to 'remedy oscillations' from ISSPRO. He's sending that in the mail and I'll wire it up according to the instructions and report back about the progress.

Thanks,
Trevor
