Power Supply Transformer

The power supply I have for the ST-35 project was custom made by Electra-print. According to Jack, "This will power a tokomak."

Here are the specs that came with it:

• Secondary is 310-0-310VAC at 200 ma DC
• 6.3V at 3.0 amp windings for filaments
• Primary is 120VAC 50/60 Hz.
• Measures 5 5/8 inches high X 3 3/4 inches wide by 4 1/8 inches deep over end bells.
  
• Mounting hole bolt pattern us 2 15/16 inches by 3 5/8 inches
• 9 lbs

This thing is a monster!!! Now I need to figure out what to do with it.
