What I do is build the lot up from scratch. Choose a circuit, choose a box, get
the parts and start building. If you are anywhere near Kensington, London, drop
in and you can leave with whatever you want - built, part built, kits, chassis,
valves - whatever. I have a lot of surplus stuff right now, so it won't be
expensive.
I started by repairing existing amps, and still have some Leaks lying about.
When you start running out of room in those chassis, it pays to build bigger
because you really need some big parts - chokes, polypropylene caps, that kind
of thing. I've gone over to 19" subracks. I like it because it's modular,
there's plenty of bits around, it's nice shiny aluminium, and turned on its end
it looks surprisingly like a Nagra! There are all sorts of possibilities with
subracks. Otherwise get a chunky top plate in thick aluminium and put a wood
frame around it (various skirting boards fit) or use a 19" case, something like
2U. I bought a few from Maplins that have perforated tops, which are ideal for
fixing stuff to.
Choice of circuit? How about Allen Wright's stuff. He has circuits on his site
- good modern designs. Well worth a build.
