Hi from the 'tipodes,
Recent posts suggest that P.C.B.s won't float on
water.Is this a reasonably conclusive test ?
A 1924 text which I'm reading speaks highly of zinc
for multiple stationary s-gaps. Could anyone comment ( or direct me to
previous posts ) ?
I've been lurking in the wings for a while now, and
enjoying every minute of it .Many thanks for a terrific exchange of
information.
Regards
Neil Walker
