F5 Ground Loop hum help please
There are 2 ground holes betweeen the caps at the opposite end of the input from rectifiers. Put one leg of the cl60 there. Other leg to chassis.

Here is an example from one of 6L6ís build guides

I'm using shielded twisted pair on the inputs with the shield grounded to the RCA jack ground. Runs nice and quiet.
