I'm thinking of making a headphone amp and have found various sites with
circuits.

I've also found the circuit diagram for the Grado RA1 amp, turns out to be
a single chip of £0.50 value and a few resistors, it gets great reviews
and costs anywhere between £350 and £400. It is in a mahogany case though.

I intend to make mine in a roomy Scottish Shortbread biscuit tin we got
for Christmas. I do also have an old, smaller and thicker gauge but rather
battered Smith's Crisp's tin from the 1950's does anyone think that
vintage tins may perform better than new ones?

Only if you build the Elektor Electronics valve headphone amplifier ... d;~}
