On the off chance someone in my circle knows...

Fender amplifier schematics seem to commonly have a warning attached to some components, saying "DO NOT STUFF". On the schematic for a cheapie Chinesium Fender Frontman 10G that has just decided to fail immediately after the 2-year warranty ended, it's attached to half a dozen capacitors.

I don't know what "DO NOT STUFF" means regarding electronic components in a circuit. I've done some searching (and will do more tomorrow, it's late) but all my results so far are more schematics for other Fender amplifier models - and there are a *lot* of them.

So if anyone knows and could point me to an explanation, I'd be forever grateful.

@cazabon unless Fender uses it in some special meaning, it usually means "don't place this part", e.g. when the same basic circuit or PCB is used for different devices or variants, or the part is only needed sometimes for another reason.

E.g. from a quick google some Fender circuits seem to have "DO NOT STUFF" parts on circuits where the corresponding part will be added on a Deluxe version of the same amp?

Thanks @HeNeArXn and @RanuRat !

I had wondered whether it meant do not populate, but the schematic is specifically labelled for just this one model. They must publish multiple versions of this schematic for each amp that uses this circuit board, and just change the title and these DO NOT STUFF markings.

I'll be having it apart today. Apparently these things are famous for being built down (WAY down...) to a price so there's lots of breakages to look for.

Might not be that there were variations of that product using the same PCB, but simply that there were optional components to provide extra features such as for debugging the board.
Maybe it was overengineered and testing identified which components could be left out and still have a viable product at reduced cost.

@cazabon I’m in agreement with the other comment here, it means “DO NOT PLACE”.
It’s almost like EE slang?
The other term they use a lot is “stuffing options” which would be component selections based on some option. For example a 24v power supply vs a 48v one. They would have different stuffing options.
