[MRCA] T-195 Power Supply Options

[B. Smith]

    It is always good to hear members of the list using  supplies  powered 
from the AC mains for their high current applications, this way you can keep 
those batteries and the hazards associated with them out of your living 
quarters.
    Ted and his famous retro rocket power supply can be seen at:

| Steve,

| Thanks, glad it's proved to be so successful.  The husky transformer
| in the old charger had a 24 volt center tapped secondary originally
| used with a full wave rectifier.  Primary was tapped giving a range of
| output voltages.  I just hung a full-wave bridge on it and a bunch of
| computer caps on the outside of the can shaped enclosure.  Simple
| brute-force supply.  Found a suitable transformer later at a 'fest in
| PA and built up a similar unit in a nice cabinet which I use to this
| day.
