[sdiy] Drop in replacement for Op Amp?

[Tony Allgood]

>They are labled CA 3080 and 422

They're not op-amps, they are OTAs. And in that unit they are probably
used as VCAs or something similar. You'll need to replace them with a
CA3080 or LM3080. The metal can types are still around but rare.
Alternatively, you can with a bit of additional wiring get a 8-pin DIL
type to fit. Pin 1 on the cans is still pin 1 on the newer packages.
