I already started saving .........
You probably reverse engineered it already from the photo!
Where are the picks of the inside?
Reviving this (old) tread.

Pass Labs Two-Chassis, Dual-Monaural Xs Series Preamplifier | Dagogo | A Unique Audiophile Experience
The one and only
UGS , core cascoded , outer ring with Toshibas
OP servo , so DC coupled all the way
that's more than enough of Real McCay , for open public forum
And do I see two optocouplers to bias the Toshibas....
And two voltage regulators that are possibly regulated by the OP servo?
But I am only a lost soul hallunizinating.....
Interesting thoughts. Not positive those are opto's, but very possible. Makes my head hurt to think about. Servo is probably both simple and another point o manipulation. Unity gain FE could setup interesting output. Transformerish. If your hallucinating, I'm the walking dead.
