I used a standard ALPS potentiometer. Since it does not fit the usual way, I simply glued it with epoxy to the inner side of the cabinet together with a piece of hardwood. I was only glad to get rid of the balance potentiometer, I have never used them.
The picture suggests some other changes, as you can see. The only active circuit in use in the amp is the opa627. This simplification has allowed me to throw out, or shorten, most caps and switches in the signal path. (I have lowered the supply voltage to the opa somewhat).
Everything has worked to my complete satisfaction for a couple of years
