i got a switching power supply to use till i can fix/replace my pp7b, it has come with no instructions so i just want to confirm how to wire up...
i plan to tap the 0/120v terminals BEFORE the iso transformer. is that the best way?
there are 3 inputs on my switcher, ac/n and ac/l which i assume are live and neutral. the third terminal is just a symbol, i know it is ground, my question is whever i should connect the green DK grounding wire to this terminal?
thanks!
also while my pp7b was working i noticed the game seemed to run fine using just the 10p line and the ribbon cable, which means the game was only getting 5/-5, so what does dk use the 12v for? can i do without it? i am using a new monitor and mikes inverterboard which are powered seperately if thats anything to do with it...
