Well, what I originally intended to do was very similar to that. Before a couple of days ago - and finding out about the quad opamp version of the OD1 - I had scanned and meticulously "traced" the OD1's PCB with that exact intention. If anyone out there that has the quad version could send me a scan of the PCB (top and bottom) I would be incredibly grateful.


On its way to you soon sir !!

SD-1 to OD-1???

Mike,
A few questions,
Is there enough room for a small daughter board with the quad chip?
Which quads did you try?
Hmmmm, is it a matter of paralleling the opamps? I wonder if piggybacking two duals would work fine.
I'll have to take a look when I'm less tired.

IN this case it's easier to cut traces and run jumpers than a daughter board. But you just gave me an idea... tack 1/2" wire leads onto the quad op amp chip. Use a 1" lead on pin 4. Then you can move 3 of the legs down one slot (4 5 and 6) and pin 7 can go to pin 4, saving cutting of any traces.

I also forgot to mention that you have to bend leg 2 and attach to leg 1 on the chip and leg 13 to 14 (leave holes empty on new pin 2 and 13).

It's not so easy to describe but you can figure it out, that's why it's called DIY  Cool
