Re: Star grounding - putting it into practice quote: "Maybe it is overkill but I consider the ground wires to be either signal return leads or voltage return leads, and treat them accordingly. Running leads parallel to each other can have a parasitic effect so I try to keep them separate and have them cross them at right angles whenever possible."     On my Humble clone I used the stock Bassman board and built it up on that. Some of the grounds were combined but all the wiring was run straight up under the pots and then all the way to the end of the pots where I had terminal strip that everything was soldered to before going to the main ground point. I wanna say the wiring for the pots were stuffed under there also to some degree. I would have to look to be sure. But I got away with it, the amp is very quiet even in the distortion channel. Guess I got lucky, I'm sure Steve's got some valid views.     My 66 I just rebuilt, using the stock Fender ground points/wiring. That amp is also dead quiet.     Just for the record, I used metal films throughout both amps. I don't what this adds to this thread, but thought to mention two grounding examples in the same chassis.     bw
