I had an Amiga many years ago, but the kids took it over. I still wonder what happened to it.
Well done for a clever and well implemented project!

As the PET had a built in CRT and associated circuitry, this meant that you were directly modifying its line and frame scan rates. Not sure how much truth there is in it, but I once heard that if you set the line scan rate to a setting where the LOPT was particularly inefficient you could cause it to overheat and sometimes catch fire. There are times when I wish Windows had such a feature!

Very happy times, even built the 1200 into a mini case years before they were widely converted. They were used for rendering some of the first CGI graphics shown on film and television I believe.
The A1200 is still in the wardrobe, I wonder if it still works.

The fix I found is to remove the unit from the case and power it up. They usually spin without a data cable connected.
Hold it up in one hand and tap on the corners with your knuckle so that the case rotates sharply in alternate directions around the platter axle. This often frees them up.
