It is always a pleasure to welcome a Polerouter Sub fan.
I'mwaitnig for your pics, and then we'll see, but I can already tell you that finding NOS dials and plexys is a tough mission.
The important thing with the Polerouter Sub is to find a nice example, and to ap^y the according price on it, because if you add to the initial price the NOS plexy and the NOS dial ( if you ever find them ), it may be quite expensive, at the end.
First show us your pics, then we'll speak.
Best,
Nicolas.
