Got my vibe done

[jjucius]

Just checked my neovibe and it works great  i tryed one of those rat shack bulbs and the wire leeds broke. but i found a bulb anouther electronics store here and it works great it has two pins comming off it to solder right to the board. the only numbers i see on it is 7371 . now if i could only get my fuzz to work. its a pnp neg ground and all i get out of it is a motor boat sound at full volume. since i'm putting three effects in one case i was hoping to run off of one pwr supply. what do you think should i switch it to pos ground and run the fuzz only off a 9v battery? or does anyone know how to make it work w/neg ground?
Thanks for your help
