Apart from some teflon wire (thanks again Pete), Mouser had most of

Thanks though. Other ideas ??

===================================
For large heatsinks (perhaps not precisely the type you need ) flea
markets will be a likely source . Otherwise there might be an
electronics surplus store in your area .
Some time ago someone gave me a clapped-out (probably illegal) CB
amplifier (of Italian origin) with a heat sink to suit your project
........however I am in Scotland- UK ,otherwise I would be happy to
send it to you .

Thanks for the thoughts Frank. I would not have guessed this before the
fact but I'm finding that tracking down / scrounging these bits and
pieces is actually fun (I am also sure that there is great probability
that I will rue these words...). Thanks again all.
