I'm calling it fixed.
With the assist from TEch 21 Support , and a couple of emails.
From Tech 21:
<<Be aware the Power Engine 60 utilizes a ground independent transformer, which may pick up hum from the auto-switching power supply. Therefore, the XLR input of the Power Engine 60should be grounded. You can make your own grounding plug by modifying a male XLR connector by soldering Pin 1 to Pin 3 and inserting into the XLR input of the Power Engine 60 per the diagram below. NOTE: If you're not into soldering, a Tech 21 grounding plug is avail-able for purchase. Please see our website Accessories page for details>>
I found the original manual, Celestion amp handle tag and the grounding XLR plug in a zip-lock bag from the original purchaser.
The PE amp is now as quiet as could be expected from any amp/effects combination.
It's done and on the slight chance that someone else has this issue, this post will turn up in a search and be of assistance.
Now onto my Yamaha G50-112ii :lmao:
