geoffkait,
No worries, I still do good things for humanity. It is just that I tried doing a few small experiments here. Like changing direction of wires or removing the cover from an amplifier. Responses, yours included, revealed more about responders than expected. Unless one strives to uncover different personality traits/flaws of others, I would not recommend posting own results of some experiments in these threads. They do not contribute to discussion about whatever is discussed.
