Of course I'm having to build a battery supply for the mystery box. I found this info once and now I can't find it again. What pins on this 4 prong male plug in the Mystery Control do the battery leads (+ and - 3 volts, + and - 45 volts) hook up to? I was able to figure out that the "Red" wire is for the plate of the 30 and the green wire is for one leg of the filament. Lost on the other two. Yellow wire and black wire. This 4 prong male plug is the one that plugs directly into the old battery pack.
