tintinambulation -- been in the vernacular too long to be considered a "neologism"
The Aleph series was ground breaking at the time when compared to other solid state amps. Yet it sounded like an average transformer coupled old tube amp of yore. The Aleph was on the dark and full side of neutral with better bass of those old tube designs of the past. Pleasant to listen to. It did not outpace a well designed tube amp of the time. The Aleph sounded like it had your average transformer in the signal path.
you just forgot to say that is nothing wrong having average transformer in signal path , as long preceding stages are up to task
Nothing wrong with a will designed transformer in the signal path. I use a transformer volume control. I have no desire to go back to an active line stage.
baaaad Papa , baaad !
pulling my leg now ....... to draw (another) Babelfish M2
it seems - you have impression that ZM is too calm these days
Papa lo longer shows us full schematics, just because he is having great fun seeing us wonder what's in a box 🙂 Now the only way to find out would be to send one half-finished M2 to ZM, and he will fill out the rest
naah ......
we already know everything needed , tnx to JapZMs from start of the thread
buff-iron-lightning follower stage
Papa send me haiku , freely translated as "ZM's head is full of ...... redundant parts"
maybe , just maybe , one day I'll learn how to achieve elegance and grace

Papa,
Question for you - have you ever tested the M2 on speakers with sufficient impedance to remove the need for the autoformer? You've said the performance of the autoformer drives the distortion performance - what happens when it goes away into a, say, 32 ohm load?
Thanks!

The autoformer sees a high impedance load (the Gates of
the Mosfets in parallel with several Kohm) and this load
is pretty independent of the speaker impedance.

My understanding is that the M2 is architecturally similar to a B1 driving a step-up autoformer, which drives an F4. Details are no doubt different.
Removing the autoformer removes the gain. Upping the impedance merely cuts the power further.
The most interesting detail is the bias circuit, which locks
the bias value to high precision but allows excursion
beyond the bias point (Class AB) without altering the bias.
I would patent it if I believed in patents anymore...

There is a small review of M2 at tone audio
http://www.tonepublications.com/MAGPDF/TA_041.pdf on page 23
That is very positive........
I am still waiting for the full review promised one year ago here on page 179
http://www.tonepublications.com/MAGPDF/TA_034.pdf
"Watch for a full review shortly when I have time to peel the smile off of my face. Nelson Pass has done it again."
Hope it will come soon......🙂
