My question: is it possible to fire this rig with my 25 amp Astron
2-pole 13.8 volt PS, and if so, how do I wire it to that big square
plug?

It would seem better to locate or clone the correct NCX-3's mobile SS
12v supply/similar; surprised to hear some say it can't be run of 12v
as-is when it was designed to do so. FWIW I have both supplies & the
rig (not interested in separating) - the mobile supply is compact &
fairly simple AIRC from its schem. Wouldn't mind parting with it cplt
for a tempting offer (not a giveaway).

huh? He asked if he could wire his 2-pole 13.8 PS to the square
plug on the back of the NCX3. The answer is no.

My advice is to get a Heath HP-13. These are about $50 on the Bay
and very plentiful. I have two for my 3 SB transceivers, so that
leaves one extra out there.

I'm not itching to get another HP-13 either as I have the Heath DC
supply and as you point out, I could use a big 12 V supply to run
the transceiver using it.

I'm sticking to my (and the others) point. If the NCX AC supply's
transformer is good, fix whatever else is wrong. A bad cap or
diode, a bad switch, whatever. Everything else in there should be
cheap and simple to fix.

If the transformer is bad, sell it on eBay as "Bad Transformer -
Full disclosure" Someone will buy it for the case or will take a
shot at fixing the transformer. Get a Heath. Folk use the Heath
for everything.
