Thanks to both of you for swift and very helpful replies.

I've made a search for the tube data but can't find anything. The label states, "NEC 370KTB22 - TC09, No. 30704288". The white plastic surround at the end of the neck tube has "JVC" embossed on it.

The ROE 1000uF 40V capacitor has failed with no visible signs. Given what was said about having to change these often, does the circuit design lead to frequent failures of this capacitor? Should I stock up? I appreciate that a loft stored monitor from 1983 powered up in 2019 will present very different failures from its day.

Fusible resistors aren't something that I've seen before. Is it possible that they can fuse without any visible sign? I'm currently determining which are fusible from the circuit diagram and parts list.
