Tried the sandpaper thing and the flux trick. Neither worked. This was a newer batch of CTS pots and the first time I've ever had that problem (been soldering 30+ years) I use good solder (Kester) and a good iron (Weller) and these pots just stumped me. Previous batch of pots did just fine. Thanks, GW

Thank you! That confirmed my suspicions, question arose from the recent purchase of some pots that solder will just NOT flow onto properly, no matter what I do. I was thinking about the buss bar idea exactly as you describe, just wanted to get some verification of the thought before doing the work. ...

Every amp layout I see has the grounds going to the case of the pots. Is there any reason to use the case of the pots? Or is just a convenient location to attach grounds?

Thanks
