[sdiy] Euro Synth Spec

[Tom Wiltshire]

If you work on stomp box circuits as much as I do, a proper +/-12V supply for op-amps seems like a luxury after being stuck on single-ended 9V for everything.

Rectifier or series diodes to provide polarity protection is a good idea, but not as vital as it is in stompbox-world, where everything gets plugged and unplugged more often. Eurorack is a modular format, but you generally install a new module once and then only unplug it a few times if you decide it might be better somewhere else.

Is that true? Are all you people re-arranging your modular every weekend?!
