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?

Could you list the parts in a Grado RA ! amp and a link to the circuit
diagram

ta in advance

The parts list is unnecessary as you will see :-)
