Have you done anything with this ISO? Looks like it's just as simple to use as a normal opamp. I was thinking about doing a rg100es type of amp. I got the transformers that I raped out of an old pioneer stereo amp. This opamp would make it simple for a stereo output amp.

i have not... they are expensive. i was thinking more along the lines as application for a PS regulator for the screens of a higher powered bass amp using 6550s or 6146s.

if i were to build an audio amp around an op-amp - i'd use this (http://www.national.com/an/AN/AN-1850.pdf) device.  :)

That looks like some thing I can work with and I got tons of aluminum to make heat sinks with. Might just be able to use eyelets with it if I can space those legs out right.
