n00b question: i have bias points, but where do I ground?

Hi, I'm new to this forum and pretty new to tube amps. I have an amp that has 4 6L6GC's and a bias point for each and a trim pot easily accessible from the top of the amp, but I don't see a common ground to use. I've been searching around but can't find what I need to know :). I could buy/make tube ...
