I've got one of these, would anyone like some photos of the board?

A schematic can be found here (not by me):

Background:

Several years ago I was given a tangle of wires, pots, PCB etc. by a band mate which produced a slightly muffled overdrive sound that I wasn't too impressed with. I built a makeshift enclosure for it and tucked it away in my loft where I completely forgot about it. A few years later I found it and swapped it with a bass playing friend for something else, he quite liked it as a bass OD so all was good. I actually tested it out first and it was much better than I remembered, probably due to having a better amp. It reminded me of a DOD 250/MXR Dist+

It has now found its way back to me, non-working.

'Someone' has tried to fit a DC socket using a chassis-grounded socket. The story goes that it hummed really badly so, thinking that the polarity was wrong, they flipped it to centre positive...now it's dead.

Great, thanks a lot. Could you measure the board dimension for me? I could draw repro layout...

Thanks :thumbsup

Here's first version. No component layout yet, and I'm not sure pot scaling. I'll do more work tomorrow

Pot sizes are 3/4" (19mm), spacing between pots (centre - centre) is 1.7/8" (36mm)

The posts which connect to the pot lugs are spaced 1/4" (6.5mm)

The spacing should read 1.7/16"...my imperial measuring skills are lacking :oops:

I can't seem to edit my posts in this forum
