- The full wave bridge from the transformer is labelled VARO207T. Does anyone know what that would sub to? Yes, know many might work, but anyone had experience here? The output is shorted, upon turn on

- randy, it is also possible that the regulator is not working and CAUSING the scr to trip. can you measure output voltage? or is zero indicating a shorted output line is the 20 amp fuse popped? It sho

- try NTE.com or simply enter that number in quotes in a Google search. THAT may bring up its spec sheet. As long as you use as much current rating or more, and PIV or more, any bridge equal or greater

- The rectifier is typically a 20 to 30 amp rated at 100 PIV. You can disconnect the leads and measure it as 4 diodes using an ohm meter. It its good then no replacement is necessary. Lift the crowbar

- If the Pass transistors are getting hot, I would suggest you check across the positive and negative output leads with the supply unplugged. If you see Zero Ohms or a Short then it is probably the Cro
