Nice sounding amp Trev.
I have recently experimented ironing on a laser printed layout to sheet metal for a power supply I am making, it can work very well, and I feel sure it could work just as well with lettering.
Print your lettering in mirror form, tape the paper with the lettering onto the metal face down. Then wipe over the back of the paper with a cloth wetted with white spirit.
Get the wife's best iron out on full heat and press onto the back of the area where the printing is. (white spirit and heat may melt the tape so make sure you keep the heat away from the tape.)
The result can be very good, you can get al;most all the print to leave the paper and adhere to the metal and you can actually feel the thickness of the print standing proud when you run your finger over it, and it does not rub off even when scratched with finger nail.
Some experimentation may be needed but It is something I will try again instead of using letraset, or stuck on labels.
I saw the process on Blue Peter years back being demonstrated by Valerie Singleton when they made some DIY printed T shirts.
The fainter lines around the transformer were my first attempt, but the final transformers footprint was smaller than planned.
