well dan M could dunk that variable air capacitor in a glass of water and see what happens to the values... leseee assuming air = 1 and water = 70..... 750pf * 70 gives us a .5mfd varaible cap :-)just looked at the dielectric constant table... water is closer to 80... but get this... hydrogen peroxide is a whopping 121, anybody know how stable this is, and how it might respond to voltage potentials??? and for those of you whio had to know, cocaine is a mere 3.1, so save it for insulating your transformers.

I ain't gonna stick no capacitor in no stinnkin water! :) I've got enough project brewing without some wacky thing like that. I just want to know if these sound at all good before I plunk down some $$Dan

sissy... use them for cathode bypasses or for filament supplies... don't go tossing the plates out with the bathwater...dave

Looking down your list dave I suppose bath water comes somewhere between urea and h2o, about 2 then!
