PB,
It's not U/L. The OT path is coming out of a PCB and to a terminal block next to the OT. I am using the terminal block to facilitate ease of removal for changes/mods, so that may negate any noise controlling measures, like twisting, but I need the quick and easy removal that the term block provides.I assume that if it was U/L I should twist the plate and screen wires together? The PS is a simple CRC and the OT B+ comes off the reservoir cap, so I figured it might still have a lot of ripple.
