I am looking for a 138307 control board, need the colors off the R90 resistor.Mine is burned. Judging by how much grinding dust was on the board, it's probably just that one and no others. Everything else looks pristine.Photo for reference. Miller Syncrowave 300(s)Miller 330 A/BPMiller CP-200 Haas / Kamp'd / CP-300 in processMiller Radiator 1Miller 30A /S-52E feedersHobart GR-303
Reply:Hey 86TurbodslI looked up the R90 resistor in my manual and it shows it as a 100 ohm resister 1/4watt Brown Black Brown Gold.My board might be a little different than you board but the R90 Resistor is mounted in the same place.Here's a thread from back in 2016 with a photo of another board showing R90 Scroll down to post #12https://weldingweb.com/vbb/threads/6...-no-arc-output I hope this helps.

Reply:Thanks Doug, i saw the other post you made on R121 and saw the value. I replaced the resistor and cleaned the board. I hope that takes care of it. If not, i'll be diving in the deep end.Miller Syncrowave 300(s)Miller 330 A/BPMiller CP-200 Haas / Kamp'd / CP-300 in processMiller Radiator 1Miller 30A /S-52E feedersHobart GR-303
