WE212e is "top shelf"...meaning you'd have to put the amp on the TOP SHELF of your rack!
If going down that path I'd look up Nomuro-san as well as he has the most experience.
GR finished our 'experimental' amp. The proto is in Greece for testing but not yet un-boxed. No idea how it works.
The next project may be this Spud - EML call it an OTA (one tube amp) - based on the EML 20B tube with Lundahl iron.
The 20B acts as driver and output tube like my 6CL6 Spud.
This Spud/OTA also uses Lundahl interstage transformers.
It shouldn't be that pricey because very few parts - if one spares the fancy casework.
EML give away the schematics, but not the tubes or iron....
Seems you heard a lot of different glass over the years. Ever get a chance to hear the WE212e inside an amp? And will the studio be turning out another amp for you like the one in Greece?
Nomura-san would have me selling way too many things!
