Hi
Just thought that it would be possible to power relays from e.g. +/- 12 V supply lines instead of a single 24 V. That would make our beloved ground essentially free from any switching currents (even more free than just running a separate relays ground), which might help a good deal for low-level swiching (mic preamp) or for large systems (console). The only disadvantage I see at the moment is the more complex PSU. Any thougths? Allready done?
