Hi WelcomeToTheMachine
Can you please be a bit more specific.
I can't make out what you are really asking for, & is it for any particular pedal/s?
Regards Dr. Bob |

Well... I have this mutilated HM-2 that I'm planning on re-housing with new jacks, LED, switch etc. But I have absolutely no reference:
 I'm trying to figure out where solder pads 1-6 and 18 go (which ones go to ground, and the rest). |

Thanks, but none of this helps... 
I already have the schematic, but get this: I can't read schematics.
All I need to know is where the wires from the solder pads 1-6 and 18 go. A picture or just a description would be fine.
PS - I've already looked at the pictures on the Boss Guts pages, but neither of them showed where the actual wires went.

Still looking... |

The schematic on the link I had in my previous post includes some useful numbers.
For example, the following numbers on the pcb are connected as:
1 -> connected to the the ring tip of the input socket. 2 -> connected to the dc jack (adapter connection). 3 -> connected to sleeve of the input socket. 4 -> connected to the dc jack (battery connection). 5 -> connected to the ring of the output socket 6 -> connected to the tip of the output socket 18-> connected to the on-off switch

Hmmm.. Aren't there two lugs on the switch?
And... Could you possibly be a little clearer on the wiring of the DC jack? I'm not planning on using the battery snap, so I won't want to wire that in and clutter precious box space.
I feel like a real pain in the ass right now , but could you possibly do a diagram in MSpaint or something?
Really - thanks so much everyone for all your help so far! Only a little bit more to go.
PS - on the daughter board for the pots and LED, one of the LED's solder pads was denoted by a >| symbol. Does that indicate positive? |

| Wait got it, the other lug goes to ground... But wait! Does it matter which lug I use for ground? |

There should be 3 lugs on the dc socket. The middle one is ground. The other two are for the dc adapter and battery.
The battery lug gets disconnected when you plug-in the dc jack of the adapter. This is one way to distinguish the dc adapter and battery lugs. |

Good luck with the re-housing.
A Biiiiiiiiigggggggg thank you, CCTSIM, for the link.
I was searching for the HM-2 Original Schematic for Years..... |
