Building "the best"

[Luckyme]

Hi! i am a norwegian diy freak! I was thinking on all the "junk" located at warious junkyards etc. I`m planning on going to such places to pick out parts from thrown stuff to build a realy great amp! I am technical electrician educated, so i know some things already. Can someone give me suggestions on good transistors etc. to look for and also what "junk" that contains these parts. Example: any of interest in TV sets, TIG velders, Copy machines etc..

Things to scrounge:

Heatsink, filter caps, transformers, sheetmetal.

A new pair of output transistors to build a 100W amp cost $4. You're not going to find them in "TV sets, TIG velders, Copy machines etc.."

Yeah I second DJK the expensive bits are transformers, filter caps and heatsinks, everything else is gravy.

You won't find "the best" looking in a junkyard, but probably the 2 most invaluable things to look for would be welders and car battery chargers. They will have nice big transformers that can possibly be used in an amp. Second to this would be anything electronic of course, but with SMPS's so prevalent, it is hard to find good transformers and large value caps in them. They often have usable heatsinks in them.

Anything with vacuum tubes can be scrounged for the tubes, sockets, and transformers. If you don't use them yourself you can always sell them on eBay.
