After ordering and assembling one of those¹ "red" 0-30V/0-3A power supplies from eBay/AliExpress and taking a bit of a closer look at it, I'd like to replace the TL-081 op-amps. It's working fine with the specified 24VAC input, but two of the three op-amps are being powered at a total of almost 37V, definitely beyond their Absolute Maximum Rating of ±18V.
The only op-amp I've used before and know to be cheap and readily available and that handles higher VCCs (up to ±22V) is the NE5532, and that's a pin-incompatible 2-in-1.
How do I find another op-amp that is (a) still available, (b) affordable, (c) pin-to-pin-compatible, and (d) happy with, let's say, up to ±20V, so that it would work as a replacement for the above-shown circuit? Edit: as long as the other pins are a fit, I don't much care about the presence/absence of the null-offset pins (the ones which have RV1 connected to them).
