We'll need a PT, Hammond 261G6 is what I used for my 5687. ~$30
Filament supply, 12.6 V TX from RadioShack ~$13, + caps and LM317 ~$6
One 5687 and socket. ~$15 Output coupling caps, $7 for ASC oilers at Allied. One 6CA4, socket and two 1N4007 for a full bridge, ~$15. Hammond 30hy/40 mA choke and 2-400 uF 400V cap, ~$25.
Mosfets and heatsinks and resistors for a Pimm-style CCS ( output from his 'mu' output ), ~$15.
Choke input supply, CCS loads and 5687 amp. for less gain, try 12B4's.
Looks like ~$140 by the time you get everything. It will kick some serious can, I guarantee (with Justin Wilson cadence )!
