Jim,
I have a few old Fairchild transistors that would drop right in.
They are AY9139 60V 4A Beta ~50 PNP Si. Much the same as 2N1701.
Let me know and I'll pop some i the post.

I'c curious, what is so strange about the pass xistor in the PSU that you
can't replace it?
Getting one.
So far I've found places with $300 minimum buys.
However, as I write I can get one for $30 including postage to
Australia. Still expensive.
Unless anyone has a 2N1701 lying around?
Regards,
Jim
