Fender Princeton brown face 6G2 early 60s full service. 

I have a "White knob" Princeton from '64. Nice amp your working on here, she's in the right repair shop.

What a beauty, and in lovely nick. That goopy cap packet looks like it belongs in a Carr. Do I see a couple of holes in the chassis between the caps and PT, where a terminal strip could be mounted? Interested to see how you tackle this.
