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.

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. Last edited by rock4016; 13th May 2011 at 10:45 PM. |
