[Snipped great report on Z-foils, thanks Frank...]

Hi All,

Are the VAR type "naked" z-foils good for anything? They seem targetted
at the audiophool crowd. I was wondering about a DIY hermetically sealed
assembly. For example could it be mounted in one of those big old
crystal packages and hand soldered for sealing? I have never tried to do
this but it seems feasible.
