Ian,
If the PR-25 is anything like the PR-40 then it uses the ubiquitous 723
regulator circuit that has been around for 30 years. Most of the highly
touted Astrons use the 723 circuit so an Astron circuit might be a good
place to start. Data sheets for the 723 are available on the web.
Re: tripp lite pr-25 (Reg Board Retrofit Available)
Although you can't really tell by the number of group posts I
make... I'm pretty busy right now. But... if you don't receive
a copy of the Tripp Lite Power Supply diagram... I might have one

I am in the process of repairing a Tripp Lite 50A power supply.
I bought a regulator board from Skipp, who frequents this site, and will
graft it in to the power supply in place
of the defective one. The pass transistors are 2N3055's, which are common in
this application.
Just a thought.

T'was over at one of my off grid commercial radio sites yesterday

current from my arrays and the charge controller is about 17amps.

I will contact skipp and see if he has the reg. board for this unit.

Not talking about the digtal coded squelch dcs/dpl type
operation... each manufacture has/had their own cute label
for ctcss tone operation.
Quiet Tone, Quiet Channel, Channel Guard, Tone Guard, Private Line
(PL), CTCSS and depending on how far back you go some other cute
names/labels used
IIRC QC was RCA trademark and CG was GE trademark for CTCSS. Johnson used
ToneGuard for their trademark.

My interpretation is that it will be effective 30 days after it is published
