And after the starter amps, here is the ender amp:
Cost: ~$200 per channel for only Mouser internals, at least. This is (one of the) the big cheese DIY ES amps, besides the legendary T2 and a few crazier Kevin Gilmore designs. Some may argue the KGSSHV Carbon is better than T2. Alternatively in this realm, one could go for the KGST for a slightly smaller but still high end build. Just FYI.

Appox Amp$$$ qty per amp: where? use:
$60 1 T1 hammond power trafo, 360v
$30 2 T2,T3 built around fuses
$80 4 PSU PSU caps, big ones- try 680uf @ 400v?
$20 4 PSU Diodes, at least 600v, 5a.
$20. pr. 1 the top, glowing :) 12ax7
$20. pr. 1 the top, glowing :) 5965
$60 4 Bias + - .01uf, 600v.
$25 1 resistor kit 4-5w, big ones
$20 2 2.2uf film, good one
$10 1 other caps (.22uf) film, a kit will do
$20 1 Other bigger resistors, 20m and so forth
$35 1 Hardware: sockets, jacks, knobs, bobs, bits
TOTAL Amp Budget: $400 :) It is 100% possible to spend way less or fathoms more on this design. This is a rough average.
