Is it an AC10c1? They have a FET as the 1st gain stage that may be responsible for the weird interaction. They also have a large input capacitor right after the input jack that could create nasty blocking distortion if you’re pushing a large amplitude signal into the front of the amp.

It certainly is, I wonder if there’s some mods I can do if the hum isolator doesn’t fix it
The weird thing is the noise doesn’t change in volume with the volume control on the Ampero, it’s the same at zero volume

If you put a pedal with a buffer between them does it go away ? As RA said above, the FET on the input could be the issue if it has a very high input impedance, I don't have an AC10 schematic to check stuff out.
Tube amp and guitar tones straight from 1958… amazing how believable the sounds were back then, even without the modellers...

I was thinking about chucking a pedal between the ampero and the amp too, only things I have sitting around don't have buffers in them, but maybe the mooer chorus being on might be a good test? hmmmm...

Update! Tried a behringer hum debugger (dual isolating transformers) and a mild improvement, thought maybe there was something in the app for the ampero around the output jack settings, switched it from inst level to line level and BOOM huge improvement, add the hum debugger in and its very tolerable noise wise, hoorah!

Is your problem now solved?
if not, or only temporary, I have a Lehle Sunday Driver SW and I think I have a dedicated line buffer in a small box that you're welcome to borrow for a while and see if they tell you anything

Yeah tis solved, quite a lot of faffing but happy enough with the outcome now
