Sign up as a member and Fab will send you plans and instructions via email/pm’s.

Oh, and learn to read in French or use Google translate.

Well to use the Quebec forum then it is in French (as this forum here must be in English). But you can simply send me a message by this forum here and provide your personal address if you want the construction manual.

Fab, how does one get the schematic, instructions and board? I have 2 pairs of Alfet 16xx parts, enough 2SK/2SJ Toshiba laterals, torroids, regulated supply which I use with ClassA amps, heatsinks, cabinets and pretty much everything else.

Thank you in advance, Fab.

Hi Samuel
Please send me a personal message to get the construction manual. You will have to choose between USSA3 and USSA5... I may have 1 or2 pcb of an older version I think. I will check once at home.

This is a 2 years old schematics. The exact replacement is still in production and sold by Profusion:
ECW20n20 and ECW20P20

All parts are obtainable. The amp have been built recently by some members.

You just asked them in the notes at the end of the order to give you the closest color match. See the tech specs at the bottom for the the color values:

ECW20N20-S - Selected Lateral Mosfet
