Hello,
I have an original LPB-1 that I resurrected from the closet. Unfortunately the black wire from the 9-volt battery clip has broken off from wherever it was attached to. Can someone provide an image of the inside of this unit so I can see where I need to resolder this to?
Thank You,

Also, the input (and output) jack only has one ‘springy bit’ for the tip. But there is a tab that connects directly to the interior of the jack, so same principal I guess. However, it doesn’t seem like the wire would have originally connected there. The way it is curled seems like it would have connected to something a little closer to the other end.
Thanks,

Maybe that’s where it came from.

Depending on whether the effect is positive or negative ground, it could be either the black or the red. The other will likely go to the circuit, not the switch. The switch is used for bypass only.

Thanks.

November 14, 2010 at 3:26 am #112568The EH ManModeratorIt’s hard to tell from the pics, but I believe it goes to the center lug of the switch, next to the 2 resistors on the top row.

A little contact cleaner as well and we’re back in 1979!!
Thank You,
