Hi everyone, I'm starting my first tube amp build - a Mojotone kit Princeton Reverb, and would like to decide on a grounding scheme before populating the chassis. I've already drilled a hole for the bias pot, next to the bias board, and will also drill a hole for a dedicated safety ground / earth bond - probably for an M4 or M5 size bolt. Preamp ground bus will terminate at the input jack. What I'm not really sure about is which way to go regarding the other ground points - the CT, 6v6s 8 pins, bias board, bias resistor, can cap, etc. as there are multiple options. Are some of them objectively better than the others or is it simply a matter of preference? What are some considerations to be aware of? This is the Mojotone version: Pins 8 are grounded to the sockets' fastening bolts, 6.3V CT connects to the bias board, the rest to the can cap's bolts. Next is StewMac's approach: Safety ground is connected to one PT bolt, everything else to a second one. RobRob's version: and some more options involving the bias pot, based on RobRob's layout: V1 V2 V3 I realize that I might be over complicating things here and that all options will probably work, but as a complete newbie, there are things that I know, things that I know that I don't know, and most importantly (or dangerously) - things that I don't even know that I don't know, so it would be foolish of me not to consult. Any comment is appreciated.
