>>Well, I think it would help if you could explain *what* you are trying 
to protect the inputs and outputs from.  Mains voltage (what voltage? 
120V, 240V, 415V..?).  ESD??  RFI??  Just synth voltages (12V, 15V)? Its 
difficult to offer specifics without knowing what you're trying to achieve.

Fair point.

It annoys me when people assume that everybody on this list is building modulars - so I guess it's my own fault for assuming you would've known that I was talking about modulars...

So - I'm talking about modulars. Specifically +/-12V power supply, 10V PP AC waveforms, 0-5V CV and a level of protection based on the fact that I will have no control over who will be plugging what into where.

Thanks,
