Hi Lawrence,
That sounded like a really interesting job. I must admit that some of my happiest memories are from working in test or service departments. I would have like to have done more design, but I'm much happier to do that as a hobby with only occasional professional jobs. Fault-finding does take a certain mind-set, but it's something that most people can pick up with help and practice.
The biggest problem is that most circuits have negative feedback, and it's not always practical to "break the loop". Everything becomes a chicken and egg problem. Earlier I mentioned a set that is causing me grief, and I'll write that repair up separately when it's done, but I must admit that I'm running out of logical ideas and am about to change every single component until it's fixed! Even the best of us get caught out sometimes
