I'll send Oscar five 2164s as a thank you for his pioneering work. :)

I would also like to know if a simple resistor would work okay. I
believe it will. On my first parts list for the Mankato VCF, I
specified a resettable fuse and protection diode for each rail on the
power input (totally stole the idea from John Blacet), and the part I
listed had a fairly high resistance. This affected the rail slightly
and made the peak to peak outputs a little lower, but caused no
problems otherwise. I've since specified a part with a much lower
resistance, but like I say, I'd be interested to see if a simple
protection scheme would work properly. BTW, how often does this
problem really happen? I've never really had it crop up and it doesn't
seem to be a common occurence, so I'm wondering if we aren't hunting a
mosquito with a bazooka here.
