Hello, This is probably not what you are looking for, but it is a good idea that others reading this thread may pursue: Mark Johnson at DIYAudio made a panel for one of his kit designs (the Noir headphone preamp) that used a PC board without any circuity for a panel where the printing was the labels, and holes were drilled at specified locations. The downside to this idea is the need to use a PCB cad program to create the file that the PCB fabricator would then use to make the board(s) quickly and cheaply. I really hope to learn how to do this myself.

Kicad is free and very easy to use. There are numerous Youtube videos showing how to use it and as an example here is one showing the placing of lettering and diagrams on the Front Silkscreen layer. Go to approximately 15 minutes in.

This particular video shows Version 6 and the current version is 8, but it's still very useful.

I am thinking of transferring a schematic of each of my amps etc to a PCB and then attaching the PCB to the underneath of each amp so that when I have shuffled off this mortal coil, a future tech can see what is going on.

JLCPCB is very cheap and reliable if you use the cheapest shipping option.

  I will soon be writing schematics, instructions, parts lists etc. for each of my units onto a thumb drive velcro'd to the rear panel or inner chassis of each piece. This storage media has proven to be very reliable in my experience, and the use of standard file types (PDF, JPG, etc.) will ensure serviceability well into the future.

    That's an excellent idea, thanks!

    So no concerns about a big power transformer corrupting a thumb drive, or does that only apply to magnetic tape?

      I haven't seen any evidence that the levels of magnetic fields present around amplifiers can affect these devices. Bear in mind, I consider this to be a backup, something to be used if the hardcopy is ever lost or separated from the unit. It can be used down the line for servicing, or (preferably) to recreate the service info for parallel storage on paper. No method of archiving is perfect, but this seems to be a better option than simply attaching a schematic to the bottom cover. :)
