Just to close the book on this one. i have continued to work on this and follow leads over the last couple of months.
I did contact Doc Hoyer who was recommended for a rewind of the existing transformer. He had not wound one of these units in the past. He would have to do a little reverse engineering along with the winding so his estimate was on the expensive side.
I did manage to get in touch w/ a guy named Bill in CA who rebuilds a lot of vintage stuff, especially HK Citations. He also did an LK-150 and had Heyboer build a replacement power transformer in the process. I tracked down the old Heyboer job w/ his help and a build on a unit for me is in process. For anyone else trying to track a power transformer down:
Heyboer Part # is HTS-8800.
Approximate spec's are
400V-0V-400V @ 475mA (Center tapped)
10V @ 7A
2 windings of 6.3V @ 7A
