I would like show everybody my home brew power supply. I got the plans out of a '94 ARRL Handbook. I think the supply was originally for about 15 amps. I decided to upscale it a bit. Instead of using four 2n3055 pass transistors I went with thirty. It has a Miller 400 amp welding machine transformer. The bridge is mounted on top of the transformer. By the specs of the diodes they should be good for 400 amps continuous. I also have a hockey puk SCR for an OVP. PS works fine so far. I've had it up to 90 amps and held it for as long as you want.
I am going to try to put this link in this post so please let me know if it works.
