I think you have to accept that anything that has been un-wrapped from its sealed box is going to get the odd mark and scratch in the course of use. That's fine to me. When I see stuff that's been downright abused however, I do get a bit cross..
Andr'e, I know where you are, having had a manic fusspot friend for thirty years who covers everything in plastic sheets when not in use and uses cotton gloves to operate his gear. He got peed off because his Revoxes developed noisy switches through not being used. Last I heard, he'd power them up for a few minutes every few months or so to give the parts some use. he also bought a c.1900 German grand-daughter clock and wouldn't run it because it would wear out. Bearing in mind this thing had run for decades with no problem save servicing every so often, I told him he'd do more harm not running it as the lubricants would dry out..
I can't go on and I can't go back, I don't feel so matter of fact,
I tried and tried to make good sense, What's the good to try it all again?
