OOPS, That should be 270 VDC @ 135 mA not 2,700 VDC. Yikes

Subject: [Milsurplus] R-45/ARR-7 Power Supply?
Hello friends.
I just acquired a nice ARR-7 that was electrically restored and aligned by a very competent fellow (pic attached). He made a 60 Hz AC-DC power supply for it, but it was crazy expensive. So here goes. The specs I need are:
2,700 VDC @ 135 mA
25 VDC @ 350 mA (for scanning motor, which is half the fun!)
6.3 VDC @ 4.0 A
Does anyone know if there is some existing power supply from some other piece of equipment that might have similar specs that I could begin hunting for? I know there is the PP-32/AR but my understanding is that this is a 400 Hz unit (380 Hz to 1,000 Hz).
If there isn’t another commonly available PS that would supply these, I may have to resort to building one. On ebay there are transformers with multiple secondaries but searching for such a beast is very difficult. Any advice on searching for a multiple secondary transformer? And of course, should all else fail, I could make a PS with 3 transformers if necessary.
Any suggestions welcome.
