l got the Prowest on the bench. Field was collapsed but it grew to full size within a minute. It's now staying that way. Switch it off for half an hour and it works perfectly. Will leave it off overnight and see. Will need to have scope probes on the timebase board before I switch on.
Looks just a like a lazy field output valve but the Prowest is fully solid state. Needn't be the field scan board, might conceivably be the sync board or even the power supply but the rails are likely to be used elsewhere.
All electrolytics were replaced a few years ago but I can't discount one of them going funny since then.
