Thanks popart - lets hope it's not too shallow & lacking in detail. If the detail is of a similar level to Wheeler Dealers car repairs, then it should be good.

There is often a fear of showing people too much, in case they hurt themselves. I suppose, understandable - I used to buy from auction, repair & sell Video recorders years ago - usually rubber belts & drive wheels & the occasional video head were the problems. But I could sometimes see, where someone had been in there before me, that Fuses - had silver paper wrapped round them, the fuses inside were usually OK - but that did not stop him doing it ! I did eventually identify him, & pointed out the joys of using a multi-meter to test the fuses (& the dangers he created), but I think it fell on deaf ears Such is people & life.
