A TUBE Eden?

That's an abomination, clearly and absolutely unrelated to David Nordschow who was (thanks God) a dyed in the wool SS man, who at most, probably pressed by some marketing advisor, just added a 12A*7 cathode follower , powered from +/-70V rails, no need to waste a separate supply for such a gimmick.

This is just a Chinese designed (that alone is a huge deal killer) and made "I also want to be SVT" copycat product.
"Chang Yue Electronics" .... really .... ?

To boot, David was originally a "speaker man" and his wideband designs needed high quality high power SS driving them; the worst to drive them is a tube head.

Talkbass is full of disappointed guys who bought one of these heads to drive their stacked 2x10"or 4x10" Eden cabinets.

Tube amps are great at driving large boomy 15" cabinets or even larger 8x10" fridges , at the edge of clipping or beyond, where natural tube compression is evident, low damping provides artificial bass boost and bite, and limited speaker frequency response masks distortion harshness by rounding all sharp edges.

"Growl" in a tweeter equipped wideband cabinet is unbearable.

Let me guess their marketing dept next move: they will offer an 8x10" loaded with Eminence B102 and rent some office space in South Vermont, so they can call this version "South Vermont Tradition" or anything which lets them display the magic letters

Back to the OP: just search for "Eden Schematic" in this very Forum, you'll find a lot from W200 to W800; some of them will be quite close.

All designers have some pet ideas which they use in many designs, that's why one schematic is very often close enough to a "brother".

Yours might be very similar to a W800 without the tube (which basically does nothing).

I hate to self quote:

I just did and found some 10 or 15 Eden schematics ..... maybe you want me to search , cut and paste a nice clickable list so you don't have to bother?

Just don't hold your breath Mylord

Here it is. Don't ask where I got it...
Note the lateral Mosfets connected in parallel. No current sharing source resistors here,
