RK271 looks like it is getting close, but they are a fair bit bigger than what is in the 162SL. They are about 19-20mm wide, where the RK27/271 are 27mm.

You can order replacement potentiometers from DBX/Harman,
I ordered replacement pots last year for DBX gear from my local DBX distributer, worked great
