[Amps] grease for tuning sliding contacts

["John T. M. Lyles" <jtml@lanl.gov>]

Moly-disulphide lube:

Every big CPI/Eimac tube(100kw and up) used to come shipped with a 
tube of Fel Pro C100 molydinum sulphide paste, used on the copper 
anode where the water fittings screwed in.  (sorry for the spelling 
of Mo). It is an antisieze compound, which is not supposed to dry out 
even at high temperature. I have used it for other applications, such 
as in automotive work, soldering tip threads, but never in amplifiers 
for wiping contacts. It would make a real mess. I looked on google 
and got this website which distributes the stuff, now called heavy 
duty anti-seize.

There appears to be some other interesting materials here, including 
their graphite 50 Mil spec conductive antisieze, and several nuclear 
grade compounds, one with copper in it.

Has anyone tried any of these? The C100 is quite nasty, in that it 
really stains your fingers. I used it just recently on the screw 
theads of a vacuum variable cap that was tight, in my Continental 
314R1 broadcast TX rebuild/conversion. After using C100, the cap is 
smooth, and the stuff won't dry out with heat.

nice to hear some practical info being tossed around here again.
