Many thanks for all your help, guidance and advice which is incredibly welcome.
I have come to 2 conclusions from this namely, 1) have an old but usable Tektronix T935a which I have now put out on my bench but more importantly 2) I should learn to use a 'scope so that it assist me in circuit fault detection.
I'd change the emphasis on that last point. I'd say that the 'scope will assist you in your understanding of electronics.
The more you understand, the easier fault-finding becomes - that just follows on. But make understanding the goal.
A 'scope is not a magic tool that will lead you straight to the faulty component. But compared to a multimeter, it is a much better set of eyes. Still needs your brain, though

I really dont want to spending time at present trying to fix a 'scope to then use it for fault finding.
Maintaining a fleet of test gear is a job in itself. That can be fun and rewarding, or it can be a PITA.
It's nice to have a spare 'scope, but I'd suggest that valved Telequipment stuff is for the collectors - unless you have a special interest in TQ gear, I'd give it away and keep your eyes open for a more modern spare. There's lots of choice, and prices start from £0. A basic 20MHz dual-channel model from a good brand like Philips or Hameg would be fine, and IME easier to maintain than the equivalents from Tek, etc...
