Re: AVO Mk 2 (HELP)
I'm pleased to hear that it works and you have no problems with a sick mains transformer, demagnetised meter or other expensive horror story.
Taking a piece of equipment which has been left in a shed, or stored in uncertain conditions for years and just powering it up, is so tempting, but you have to fight it. You were lucky to get away with it.
As I understand it, mould requires high humidity (80%?) and still air to grow. It may have been growing on the moisture coming out. I'm pretty sure that coil is insulated resistance wire, rather than an inductor.
I'm not sure how good switch cleaner is as a mould proofer, but if you keep the tester somewhere dry and check it every now and then, I don't think you'll have any problems with mould.
Congratulations on a right result.
Pete.
