From the post
Almost didn't draw this up since it's just another Electra variant, but they almost always sound good, so why not? This one claims to emulate the sound of EL34 tubes, which sounds like marketing gibberish to me since it's just a diode-less Electra. Originals are all hand wired, point to point, floating in the 1590BB enclosure. Super cool looking, but a major labor of love to produce, hence its hefty price tag. This will fit in a 1590B, but has 2 footswitches, so the drill template reflects a zVex-style of layout. Schematic and cool teardown vid on FSB here.

Check before you build · 2 values the reader of this layout was not sure of
- Diode by the +9v pad is printed '400X' (any 1N400x), entered as 1N400X
- Pot labelled 'Boost 3-1' on the board: the legend has no Boost pot, only 'Gain: B1k', so it is entered as Gain B1K
