Ah it is obvious you don't know johnS.
johnS is the kind of guy who if he breaks wind believes there is a problem. But by the same token, if he doesn't break wind johnS believes there is a problem. He freely admits he's a born worrier, like he admits his farther is a worrier, he cannot help it.
Get involved and you will just end up being frustrated by his logic. And for that reason, I just sigh and as a rule just click onto the next topic when I see his "what is this noise" when should I "replace this component" posts.
No malicious intended johnS, but the fact is you just do my head in.

I'm genuinely here to learn from and help others when I can, but I've given up on you mate, sorry.
