Making A Dual Opamp
« on: September 08, 2006, 06:48:50 AM »
Hey guys, first post around here. I'm thinking of building one of these DC opamps and squeezing it into my DS-1. Only problem is  my DS-1 uses the Mitsubishi M5223AL dual opamp. How would one go about making this a dual opamp? Would I simply build two and connect -ve and +ve together?

Thanks. :)

Yep, and it works.  I did that for the bluesbreaker, my post with some pictures: http://www.diystompboxes.com/smfforum/index.php?topic=43635.0

FYI-

Just in case you wanted to try a pre-made op-amp, here are two that work well, I happen to know...
This is assuming you have the SIP-8 op-amp in your DS-1.

NJM3404A

These are drop-in replacements for the Mitsubishi M5223AL
