Please help - I'm building a guitar amplifier from an op amp.

Opting to drive my class AB stage with a high current/high voltage op amp & use a rewound m.o.t at ne3055's highest acceptable +/- voltage (I think it was 60 from memory)

So far works well by paralleling 3 ne5532's together to give me enough current to drive the darlington pair's.

How do you run the NE5532 at +/- 38V, this is nearly twice its maximum rating?

Furthermore, the base current for the output transistors is provided by the 3k resistors not the NE5532 so adding more op-amps in parallel won't help.
