What's the distance between screw holes in FF?

I have a couple of Fuzz face enclosures and the distance between the centres of screw holes is 51mm.

Thanlks but been there, done that...

I have this beast so I don't need the schematic or values; I can just look at my board.

It's the OFF BOARD wiring I'm interested in. I've done a fairly thorough web search & have come up dry. Any one have any other resources to the OFF BOARD WIRING? from the pictures on the web, it looks typically 'British'.

Never seen one in the flesh but I was under the understanding that these unit where *positive ground*?? If so the then the pictures make sense as the red positive goes to ground.
Check the electros for clues as they will also be polar reversed.

Yeah, that sets me off. I did the wiring layout but stopped at battery connection. The schemo I have is for BC109, all we know thats NPN trannies....

What's confusing about the off-board wiring? It should be pretty straight forward to figure out from the schematic regardless if it's it neg or pos ground.

Not quite. Schemo screams for NPN silicons, and wiring picts shows positive (red wire) going to ground.

Ah I see. Well all wire coloring in the OP unit match all the old photos I got of other units so the off board wiring looks right. Two red wires look replaced but they we're hooked back up right, same with color. I never really looked closely at this one but yeah, the jacks are grounding to positive and the battery is being disconnected from the circuit off the positive wire so good catch there! I'm surprised that wasn't noted in the schematic in the other thread.......

Does the unit work?

Want some more confusion?

E-caps on the same picts I was referring to are pointed negative to ground!

I say WTF?

Just wondering if anyone's finished building one of these and if so, how much bass/treble boost do you get with it?..... :hmmm:

Yeah I can see the confusion now after eyeballing it. It looks wired for positive ground. It'll work either way as the electros are facing where they gotta go. I wonder why they did it that way? Did they do the same on the silicon Fuzz Faces?

No, they're usually wired up correctly.

Hello all,

I want to build an Arbiter Bass/Treble Face, but I didn't find a layout of the parts. I've tried to retrace it using the photos from this topic, but I don't have enough skills to do that.
Can anyone help me?

Best regards,
Radu

shouldn't the schematic be cool enough?

Thank you LucifersTrip!
I've seen the schematic, but in the photos I saw some capacitors that I couldn't identify. I will try again, using both the schematic and the photos.

Best regards!

If anyone saved the schematic could they re-post it? Thanks.
