Hi, I recently acquired this EHX LPB2 Power Booster from an older friend, when I asked him about vintage pedals. I have family members who work on circuit boards and things of that nature, so if possible and if I could get the wiring diagram, I think this one is entirely fixable.

Initially I tried removing the 9V attachment at the end of the red/black power cable and then splicing it to a 9V power cable that I tested and works, however the pedal isn’t receiving power. It may have been customized but is it possible for me to get the wiring schematic or diagram for this specific pedal so that I can fix it? I know people can say that there’s a new version or a better thing to do but I’m interested in fixing it.

I’ve attached some pictures of the pedal. It has the 137 on the box like mentioned in other threads however anything after 137 is soldered over. On the other side of the box inside it says WW7085. I’d be eternally grateful if I can get this guy up and running.

Thanks in advance, Mike
