That's the Peto Scott TB1204A 8.5" monitor that I mentiioned in a previous post. I used to look after several of these but they are long gone. Gave good pictures but got horribly hot. I remember stripping out all the dual standard bits to try and reduce dissipation a little. Probably not much, as the standards sensing was the only solid state part.
One of these monitors also gave me a hideous fault that took me a long time to fix. This was probably back in the 1980s. One of these monitors would occasionally suffer field collapse. I changed every part in the field timebase, including the FOPT and scan coils by swapping it with another monitor. A wire to the FOP valve heater had never been soldered. Worked 99%+ of the time.
I'm sure we have a few of those in the BECG stores.
