Audioromy schematic

[Tesla88]

Hi , i want to experiment with GU-29 tubes , i purchased some russian nice ones ...

I want to try the Audioromy schematic and i've found some posts regard the amp with some different schematics , not really clear , so i'm not sure what is the right one.

If someone have a better schematic , i would take a look and maybe test it.

Also , what is the best operating point for GU29 interms of B+ , G2 , and Raa (plate to plate load) in a PP design ?

Or , is better to use a couple doing a parallel SE ?

Many Thanks

Pete Millet has a SE 829B project, easier to follow than a schematic from Audioromy IMO.

I've found the Millet design , but is a SE ... i would try a gu29 PP

Here are the schematics of the AudioRomy FU-29.
I made them by reverse engineering my FU-29.
