Do you need service? FWIW the schematic at the first link is adequate for any technician to service the amplifier.
Need help finding spec. sheet, schematic, and or manual
For an earlier Sophia Electric Technology EL34 amp.
I have this: https://www.diyaudio.com/community/threads/sophia-electric-el34-schematic.155095/
and this

Sophia says they have no documentation since the amp has been discontinued.
They also, b.t.w. refuse to work on it because they're "too busy".
Imagine McIntosh acting like this.
