Rick,

Use a 20VAC transformer(s), a full-wave bridge rectifier, and a very large computer-grade filter cap.

I don't see how you can do this with 13.8 volt transformers.

I need to build a 28 vdc supply for my ART-13.  Does anyone have or know 
where I can find a nice hefty piece of iron for this project?  I have 
the transformers for the high and medium voltage supplies, however, I do 
need a couple of chokes. 

Has anyone had success using several smaller transformers, say 13.8 @ 3 
amps in parallel and series to achieve the 28 volts and appropriate 
amperage?  I have a bucket full of small 13.8 volt transformers, but 
they are only rated at 3 amps.

73,
Rick
