Got the supply and seems well made with an integral fuse holder in the iec socket.
The Earth is attached to the bottom of the case and there was continuity from the earth pin to the switch lever on the front.
Didn't stop me putting a 1A fuse in the plug.

Well I have listened on headphones and even recorded from the Pre-Amp outputs using the original and the linear supply.
I recorded a selection of music and placed the 2 versions on top of each other in DAW software and did A/B comparisons in real time.
And I couldn't tell the difference.

Looked at the waveforms at 1mS resolution and there is no difference.

Looks nice though.
