    Question Spectrum 375 schematic

    Hey guys, I received a free Spectrum 375 Plasma cutter the other day knowing that the main board had problems. I run an electronics repair shop but am having problems locating any schematics for the 205852 board. Also the Potentiometer on the front of the board for the output was broken off so I don't know the value of it. Can anyone help me out? Thank you!

    Was able to get the schematic from Miller as well as the part number for the pot.

    Thanks Miller!
