Interesting book on valve ageing, how to spot it, and what causes failures….

Nice find, cheers mate.

[Marco]

No worries, dude. It was shamelessly stolen from a thread on pfm, but I thought some folks here would find it useful :)

Cheers Marco, I have seen some parts of this before but not in complete form.

Some of these old publications contain nuggets of gold.

[Ali Tait]

Yes, well worth having.

Methinks a link to this ought to go in The Knowledge (under Technical). :)

[Marco]

Me agrees! :)

Also, when you get time to write that article about valves and, erm, ‘x-rays’, I’d like that to go there, too ;)
