Hi Nick,

Yep, definitely off load - that’s to say there are a few uA for the idle logic and a few mA for a couple of LED’s.

The voltage regulators always do run warm.

I’m going to take DC measurements on the scope by way of checking my off-brand DMM.

What’s odd is that there’s roughly a volt missing from the output of each regulator, regardless of its design output.

I did desolder the D-PAK 5V regulator and tacked another device in place. Same result , 4V… so it’s not a fault of the regulators. Nothing else has changed. There was a bulging cap that I spotted before it blew up but that’s the danger of using 35V rated components so close to their limit.
