If you want to pay standard consulting rate for the advice, you're welcome
to. I take paypal, even.

It will change it a lot. I think it will change it for the better. It
won't change it as much as replacing the output transformer would.
Remember these things are designed for voice-grade applications. The
input transformer has a _lot_ of parasitic capacitance in order to get
as high a ratio as possible. This gives you basically free gain, but
it also pretty much cuts off the top end.
Sowter might still make a high ratio transformer like that as a specialty
item.

RCA made a lot of their own transformers. They did use some UTCs,
although I think the ouncers and sub-ouncers are too new to have been
used in those. They also have since been discontinued so you won't be
able to get them.
The ouncers are also smaller than the original transformer.
Hmm... maybe some of the Tamura Microtran transformers might do it? Again
they'll probably be better than the originals, but a lot less so than
the Jensens. They won't sound the same on the low end either since the
are made with much more modern core materials.

If it were my decision, I'd put Jensens in. But then, I always threw
out those cheap transformers on Altec gear and put Jensens in too,
which turns out to devalue them considerably. Also those godawful
Beyer things in the Altec mixers...
I forget... is the transformer on this an octal-socket thing, or is it
mounted through a 5/8 stud? I remember it being a round can type.

Sure!
