5532 and 5534 should not have +/-20V powering them. Theyare probably only saved by the 100 ohm resistors in series with each supplyline feed. They are meant to run on +/-15V.
The 5534 is a decompensated amp and hard to get a replacementfor.
The 5532 is easy with an OPA2134 once you fix the +/- 20V supplyproblem.
That is easily fixed with a couple resistor value changes.
Change R2, R3 from 1.82K to 1.33K
Z1-Z4 to OPA4134.
The way this is done by design degrades crosstalk between the L/R channels. Nothing you can do about that.
