Important grounding question

[chaf87]

Hello everyone. I'm starting to assemble my second Hoffman 5F6-A. The first one was long time ago. I have a question about the grounding system: in the specific document on grounding, Hoffman instructs us to ground the preamp filter caps to the ground bus and the B+ filter caps to the chassis ground point. However, in the 5F6-A schematic, all the filter caps are grounded to the chassis ground point. Did I miss something? Just to clarify: when I made the Bassman a few years ago, I strictly replicated what was detailed in its schematic. Thank you very much.

One or both of the arrangements you show may work fine, perhaps depending on other aspects of the circuit's implementation.

Given where you are, you'll probably need to read it many times.

Ok. Thanks a lot. I'll read this article right now.

If you get stuck with it, don't be afraid to ask

Ok! I think I'll just follow the amp's layout.

What schematic are you thinking of, eg https://el34world.com/charts/Schematics/files/Fender/Fender_bassman_5f6a.pdf
A real 5F6a looks to have the decoupling cap for the preamp supply mounted on the circuit board.

Whatever, if you're unsure of the theory, it's a very good idea to follow a proven arrangement.
