Both the Pegasus internal tuners were made by LDG.

John,
I am far from an expert, but I seem to recall that TT used the LDG
boards early on in both the Pegasus and the Jupiter. I have seen a
reference somewhere to the change over to TT tuners. Also I don't know
where or how they changed/bought/whatever the tuner design. My memory
gets flakey but it also seems to me that LDG stopped offering the
Jupiter internal tuner about the same time.

I picked a Pegasus with an auto tuner and have been playing with it for
the last few days. I enabled the tuner and was expecting some relay
chatter and didn't get any. Now that I have a basic understanding of
how to maneuver around the settings I decided to investigate a little
more. I took off the cover and found a lose wire.
The radio has an LDG RT-11 auto tuner board rather than the PT-11 that I
seem to find referenced on Google. The tuner board has a set of header
pins similar to a normal Ten-Tec connector that is labeled J3. It has a
red wire from the radio guts soldered to pin 1 of this header instead of
a connector and the red wire appears to be the +13.8V line. There is a
green wire that was obviously soldered somewhere in the past, but is now
hanging loose. The only other wires are coax in/out lines.
My guess is that this is not an "authorized installation", but probably
is effectively the same as a PT-11 install without the proper
connectors. I can't find a schematic on line for the LDG unit, nor the
Pegasus for that matter.
Any ideas where the green wire goes?
Thanks and 73
