If you were building an RF device, perhaps so - but for a low quality valve audio unit it doesn't matter.

yeah, I know, but like I said, its free
and it also means that ground is 'available' where ever you may need it
heck, whatever, its just for fun

Old tobacco tins are great for building things in - it's fully screened, and the surface takes solder easily - either 'free wire' inside it, or solder tag strip inside and use that. I've built many projects (particularly preamps) in them over the years.

But presumably you can't solder to them?.

But rough on the transistors though

But they are very nice looking boxes.

hey, finished lacquering
Im happy with the result
but not so happy with the vented hole plate on front
looks a bit too dominating

might be better with 'smoked' vinyl

not long ago I found an old B&O receiver
it gave me a nice trafo
but I also took the frontplate with me
I felt stupid, but just thought it looked nice, and might be of use, somehow

hacking off the right piece, and voila
