Its fairly simple but very clever. I initially had the hummmm problem (earth loop) on the Fender 6G15 Reverb unit that I built but eliminated it by implementing the isolated ground scheme. The modern re-issue Fender 6G15 has it built in.

I’ve isolated all the jacks and I built a floating ground with a big 5w resistor, a cap and two anti parallel diodes on a strip of eyelet board. Then I have the star grounding style with a common return to the floating ground point
Sounds like you've already done it. I've PM'd you anyway.StrummersOfThunder wrote: ↑Fri Dec 01, 2023 6:47 amI’ve isolated all the jacks and I built a floating ground with a big 5w resistor, a cap and two anti parallel diodes on a strip of eyelet board.

Hey JB, I mis-read YOUR post thinking it was strummers asking. It's too hard to "explain" in a post, want me to send you the info?jeremyb wrote: ↑Fri Dec 01, 2023 6:09 amCan you explain this sorcery Mike?? Sounds wild!MikeC wrote: ↑Fri Dec 01, 2023 6:06 am You need an "isolated ground" - the chassis ground is isolated from earth but still sufficiently connected for electric shock safety.

Lucky for you, a certain guy that builds amps for people is very safety consciousrobthemac wrote: ↑Fri Dec 01, 2023 6:42 amWho needs safety when you have dripStrummersOfThunder wrote: ↑Fri Dec 01, 2023 6:36 amMikeC wrote: ↑Fri Dec 01, 2023 6:06 am You need an "isolated ground" - the chassis ground is isolated from earth but still sufficiently connected for electric shock safety.

HA! All good, it sounds like Strummers has explained it above but thank you for the offer!MikeC wrote: ↑Fri Dec 01, 2023 6:54 amHey JB, I mis-read YOUR post thinking it was strummers asking.
