Hah, wait until you get to do the Ikea type assembly

Luckily he wasn't too far away, so I borrowed my brother's van and did a couple of trips.

First you'll have the thingamajig next to the froo-froo valve unless it's a later model. If it is then it would be located beside the doohickey...

Yes! I think that's it! The 63rd wire from the right is plainly going to the matrix. Thanks.

The whiteboard in the background shows an inverter configured for passive resonant signal filtering, but it looks like you have the inverter wired through a pre-amp matrix, which would default to active filtering. This will certainly cause instabilities beyond 27 degrees or so.

I am, but they are cheap ones from Aliexpress. I'll have to get the mu metal sheet out and see if it helps.
