It's not Loctite, it's Electrolube, thermal bonding system adhesive.

Never heard of that one.

Why the hard nylon? standoffs? Nowt wrong with the bump-on feet you know - and these allow for a little 'give' too. I've seen a lot regarding amps that the likes of Parcel-Force have kicked around like footballs (ask Alfafan here), but the boards as mounted the 'NVA way' usually stay put.
Hanging on in quiet desperation is the English way...The time has gone, The song is over, Thought I'd something more to say...

Confused here. You have I assume one secondary and bridge creating the +ve supply, and the other creating the -ve. Should there not be a 0v joining the two?
