That's a shame. The model I had was obtained from derelict but had an equally derelict spare chassis to make one good set from the two.

Usually, when adapting a set for 625 only it made sense to remove the sliders then hard wire. Seems the previous owner of yours went too far and probably introduced faults along the way.

Still suspicious of that zener diode though. When I first got my example working I got a lime green raster on both systems which couldn't be extinguished on switching the A1s off. The zener was responsible.
