You could use most any 275-0-275v transformer at 100ma or more. I tend to like the 300 series of Hammond. They are designed for 50/60 cycle primaries and tend to be less prone to buzzing than the budget 200 series. The 370FX at $66 would probably do nicely.The Hammond 158L 15H, 75ma, 411 ohms. @ $20 would be close enough to replace the chokes I used directly.
I'd stick with the tube rectifier if possible. With a DC coupled design it's especially nice to let the tube filament stabilize before they get slammed with B+. A 5V4 or 5AR4 would work nicely.
I still really like this amp btw, still in daily use in my office.
If RockysDad or others want to report what they've used for a power supply/transformers I'd be happy to add it to the website.
