@Martin -
yup, Maggie Vibe is completely different, it uses varistors and phase effects to produce a real vibe. The "Harmonic Vibrato" is still a trem, though a complicated one. I've looked into building a Maggie vibe, but never got around to it. I found some of the varistors a few weeks ago for $130/4, but wasn't willing to spend the cash.

Current production Accutronics (Korea). Remember there is a big difference between Fender amp reverb and standalone - the standalone is driving the reverb pan with a 6[VK]6, and there's much more signal to shape (throw away) with the dwell and tone controls. If I have time, I want to do a new video that shows the difference between 2 and 3-spring reverb, between standalone and amp reverb with the same tank, and between bias-vary and "harmonic vibrato."
The schematic is on the Weber site
https://taweber.powweb.com/store/kits_weber.htm#5H15T, he calls it a 5H15T ToreT revibe, I think. Two parallel signal paths. The mix control only mixes straight and reverb; it does not affect the vibrato.

no kits from Hoffman, only the board (without turrets). Weber sells a kit, but it has a normal eyelet board, not the turret board. That may be an advantage in this case, because the filter caps fit on Weber's board, but don't on Hoffman's. I had to be creative with the cap placement. I wanted to use a doghouse, but nobody carries the small doghouse. Worms has it in their catalog, but nothing in stock. Fender doesn't list it as a part anymore, though they use it on the DR.
The Hoffman info is on the "library" page -
http://www.el34world.com/schematics.htm#Hoffman%20Board%20kit%20information. - it is the last entry under "Hoffman Board Information." There he describes how it came about, asking Weber to do a custom chassis for him, and how Tore T fixed the hum.
I am building a second Revibe; am looking for a better solution for the caps.
