Hello,
I want to get an idea about whether this circuit will work in reality. The LM337 is seen to be working as a current source in the simulation, so the gate voltage of the mosfet is high.
What I am trying to do is actually make the tubecad circuit simpler.

Without the opamp, you get a buffer stage. This kind of buffer stage has very low thd. You don’t really need the opamp.
Also check the internal circuitry of LT1010 buffer. https://www.analog.com/media/en/technical-documentation/data-sheets/LT1010.pdf

You might also have a look at elvee's regulator chip amps, like this one:
