How to replace volume pot in Dynaco Pas


I have just aquired a Dynaco Pas 2 preamp. I would like to replace the funky volume pot.I have a alps style pot and I also have a stepped attenuator to use.Both the Alps and the Stepped Atenuator have 6 lugs for connecting.The stock Pas pot has 12 lugs. Normally there would be R-in,gnd.,R-out,L-in,gnd.,L-out.That's six.
The pas has 12 and a couple of caps connected as well. Can anyone enlighten me on how to change this out?

thanks in advance.

Thanks V. I have used a 25k stepped attenuator and built myself a little one input passive preamp (no autoformer)and it sounds pretty nice using the Pas2 as a phono stage only. The weird this is;I don't have to turn on the tape monitor,it just works.
Is this normal?
