Hi guys, many thanks for the checklist and recommendations! Yes, a fundamental understanding is what I need, so that book would be ideal, I will grab a copy. I started looking for an old set somewhat naively, but Damen took me aside, opened up the back of a couple of his sets to warn me of what I was in for, asking if I intended to make this my main set or decorative. In other words, doing due diligence as a responsible, conscientious collector, which I respected and understood. Having no background in electronics, it is intimidating for sure; when you said "respect for voltage", yes, that's an excellent way of putting that. I'm 43 so I did grow up at the tail end of these days, have memories of smoking sets and grandfather's accompanying tirade, the man in the van coming, etc. But I think I am up to the challenge! Thanks for the warm welcome.
