I'm trying to remember the name of a video amplifier IC - it's an old
Motorola chip and I recall that the internal circuit was basically a
common emitter feedback triple with a pin for external compensation. MC????

Good guess! The 592 has separate input emitter current sources so you can
add a cap to differentiate or to handle large input offset voltages:

Thanks, but I don't think that's it. The one I'm trying to remember had
a bigger bandwidth (~50 mHz IIRC) and was single ended all the way through.

That's NOT a feedback triple as Bitrex asked. This is...

MC733, maybe? The NE592 was similar but would work down to lower gain.

I was thinking of that configuration today for some reason but I
couldn't remember the name or where I saw it - I recall now. It was in
a YouTube video on analog IC design...there's actually an analysis of it
here at 39 minutes in. http://youtu.be/1g50dJ4vCh8

Hilarious! But it's not "lag" at that compensation point, it's
"pole-splitting.
Also my MC4024 (and related PECL devices)...

Except that it's NOT, as the OP requested, "...basically a common
