I for one would be grateful if you could look over the PSU design that John is putting together.

There is a bag containing some highly spec'd adjustable 3A regulators on the shelf above this computer, some large electrolytic capacitors on my workbench, a couple of toroidal transformers, and a substantial heatsink in the other room... all bought for the job.
Not simple enough for Google-Bot to understand...

Mine are PMC GB1 mk1. I bought them new on the strengths of the Good reviews which noted their ability to work close to walls. I purchased them in the UK while living abroad and brought them excess baggage on the plane.  Remarkably the guy allowed me behind the curtain to where the large X-Ray machine was and I remember being impressed at the amount of stuff going on inside the cabinets, loads of intricate folds like the inside of a shell. 
What distinguishes this speaker from others I’ve had is the ability to maintain an even balance in the bass at low volumes. It gives a great deal of confidence for the bass not to disappear when you turn down the volume. 
They have definitely been along for the ride on all the upgrades I’ve made in the years I’ve had them, and love the Accession !
