Test power supply build
#3

I found a power trans that might work, although not as heavy as I want. It's about the size of a large ac radio trans. It has some pretty heavy 6.3v leads, looks like a 750v HV, but the center tap is internally grounded. I took the cover off and verified this. Looks like I could clip the ground lead, solder a wire on and run it out. I did a quick bridge hookup with the HV to the AC in, - to the trans case and + to the meter (nothing else). But something must be wrong as it overloads the trans. It's a bridge unit that I have used in other apps, but was in a hurry and probably didn't hook up right. I may keep looking. Found a few on epay from organs that would have lots of power. I have a really cool trans from an old TV that has the rectifier tube socket right on top. Just got to find it tho. A schematic would be interesting, Chas. I could use a couple transformers with the filament on one and the HV on the other controlled with a heavy variable resistor or something.
