bellari mp105 mod

The Burr Brown OPA627AP Op Amp - Will this op-amp work in/improve my bellari mp105? i've already changed the tube. the black lion modification specifies an op-amp that you can't buy any more. I'm also thinking of upgrading the pots to some that are correctly rated for the circuit - can anyone suggest some that will fit in the case/be compatible with the pcb wiring and are available to the uk?

Check out this thread. I have listed all the parts suggested by Black Lion and where to find them. They are all still available.

The AD826 is a very dirty opamp. I stopped using them back in 1995.
