Default What would you make with this power TX?

I've got a NOS 1954 vintage mil spec power transformer with 750vct@190ma, two 6.3v, and a 40vac windings. What would you build with it? Must be stereo SE.
My stuff: MC30, MC225, MX110, PAS3, ST-70, RH-84, HK A224 and a lot of parts waiting for time.

Typically 1950s transformers would have 115 or 117 V primaries. So if you build a CLC filtered power supply with 6.3V damper diodes you'd have a loaded b+ (say 135mA idle) of around 480V or so.
I'd build this.
Electra-Print.com 2A3 DRD Amplifier

If you need more B+ you could use SS diodes.

Or a Tubelab Simple Single Ended with KT88's....

Do it point-2-point, or buy the board from George.
