[R-390] Alternat for De-Oxid?

Wed, 23 Jan 2002 20:03:54 -0500

Hi folks:

I use, and have used, Stabilant-22 since the mid-1980s when it first came
out. It's very expensive, but is diluted in 99-percent isopropyl alcohol,
and it goes a long long way. It's billed as a conductive polymer.

It's a great insulator between contacts, but when compressed it acts as a
conductor (better than solder). I use it on edge-wipe connectors (on the V-F
display on my Omni-V transceiver), on my model trains (switch contacts, rail
wipers), on coax connectors at HF and below, between DIP sockets and chip
lead-frames, and on vacuum tube pins.

Recently I applied Stabilant to each and every sub-mini silver banana plug
and jack on the RF coils of my R-390 (non-A) during reassembly after a total
teardown (after a house fire almost destroyed it). It surely didn't
adversely affect anything in the RF deck. The set is very, very sensitive
and hot---even on 10 meters.

Phenomenal stuff that complements De-Oxit nicely. I strongly recommend it
for contacts that are under pressure as opposed to simply wipers (although
it works there too).

(For what its worth)

Rummaging through MISC stash I came across a sample (not openend yet)
of a contact conductive enhancement compound named Stabilant 22A. I got
about
16 years ago. Its NOT a contact cleaner but a contact improver!
