Opinions: On op amp replacement

[Tony Allgood]

As Juergen says, don't do it unless you know the circuit. I had a power
amp with 748 and 741s in, swapped them for 5534 and OP27s, and the damn
thing blew up. Bang. High frequency oscillations killed the power trans
and shorted the two rails together. Nice.
