Wavebourn Tower-III High-end hybrid amp

[kees52]

It’s been awhile and I’m curious if anybody else got around to building this hybrid amp?

This tread is in a wintersleep.

Perhaps it would spring alive if someone could replant the seeds of the missing schematics and other posts (mostly by Wavebourn) that now have broken links to externally hosted material.

Wavebourn did much tube amps and preamps, did not much to hybrid I guess. I have build to versions in past, one has a plate follower only version
do total feedbackless until the mosfets.

Seems that the design is lost. Pitty, I thought it was one of the best hybrid designs.
A search finds only a thumb nail image of the schematic.

Kees52, could you perhaps upload some of those schematics to preserve for posterity?

Wavebourn posted dozens of images earlier in this thread that he started, presumed to be a hybrid design, in ways that are now lost.

I can not upload much, I can look if I have some from the past, I did myself design these amps, last one with auto-bias, have not design
it completely myself but uses all kind of circuit parts combination I did read about. There is not much to renew anymore in this respect.
