[Boatanchors] How about a different topic relating to electrolytic caps

[Gerry Steffens]

I think I tried this on the old reflectors before QTH.net.  I did get an
answer but computers being what they are, I lost it to a crash.  So, here
goes.

I have many old E.H. Scott radios, many are the early ones which have true
electrolytic caps (the kind with the metal fan electrode, supported by a
rubber seal in the bottom, inside a can filled with liquid electrolyte).  In
a few of these radios, these are still good and functioning.  By the way,
when these dry out they don't short, they just loose capacitance.

The question:  What is that liquid electrolyte?

At the Michigan Antique Radio Club Extravaganza many years ago a fellow
demonstrated refilling these units using a syringe through the vent holes.
This saved a lot of time and work, plus the radios worked perfectly.

While this doesn't compare to the earlier discussion, anybody know what the
electrolyte was?

Just curious & thanks,

Gerry
