Little help? Which of these has a differential pair for input / can take balanced drive natively, and has a low Zout?
- Babelfish J and his cousin (not listed here, soon in Store) Aleph J
- Plethora of Pinjatas
- Babelfish XA252
- Babelfish J2
- Babelfish XJ
- Ludef P
- SissySIT P
- Il Penitente P
- Old Soul P
few more, from next day

oh yeah
did full homework
No go with additional emiter/source/cathode/voodoo follower in between input JFet and output gate, which would enable Schade iteration
This time my ambition outweighed my talent, couldn't beat additional TempCo of said follower stage, so byebye Herr Schade
Anyhow, covered entire BL range of 2SJ74 (defined critical values so functional with tried 6.5mA, 8.1mA and 10.88mA JFets)
Also covered two logical iterations - Semisouth down and IRFP150 down
It behaves, it sings, feet are tapping; both
So, another one on pile of ZML amps which all sounds the same
One of these days will open proper thread, with all gigglywigglies and other adequate porn

do not, until there is actual thread
this was just for fun and tease

Is it a planned diy-shop product?
ZML product, maybe
though, as all(ways) - once when I post schematic, nothing is stopping anyone to draw own pcb and take parts from drawer

Tim de Paravicini's amp, made by Musical Fidelity, named A1
Never made properly, in fact - made properly as one year lasting heating plate, good for Pizza treatment
my love from youth...... and I still have one
anyhow, now made properly
finally got to make some substantial changes, so able to call it Babelfish, and be happy with

Some would say you have a nostalgia problem!
MFMF A1 < Must Finish Music Fidelity A1 35 years later!
not so nostalgia as it was sort of puzzle, existing for years
first to understand circuit, then to try to understand reasons for compromises I was able to see (I was surprised eons ago when I realized how much is possible to learn in process of trying to understand constructor's line of thoughts and reasoning), then to try to devise and implement some changes ........
I made my own MF A1 clone 35 yrs ago, along with all mistakes and flaws
