It’s probably got the same feature as the 2 CFP-470’s that I have, they have a switch on the side to keep the heaters lit all the time, and another power switch coupled with the volume which is really just standby. The Instavision came a bit later, I also have one of those! It just has a really fast heating tube, although I did read somewhere about them possibly being directly heated cathodes, which were short lived. The 2 CFP-470’s have got knackered tubes, probably from living on standby! Other than that they haven’t had any replacement parts! They look like they could do with a service now though, frame linearity is suffering on one and the convergence is a bit of a mess on the other. They have 14” delta CRT’s.
