Most of us know the old uA733, it's still sold but the quantities aren't very encouraging. A whopping 34 pieces at Digikey. Big red flag for me. The NE592 is non-stock in all versions and there are a few thousand TL592. None of these were ported past SO style. That's another little red flag.
Could high-gain video amps be on the way to Unobtania? I was hoping there'd be some markets other than VCRs and older disk drives for them but maybe there aren't. Any alternatives? Sure, there are fast opamps but those cost an arm and a leg.
So, does this mean back to discrete design?
