Little help? Which of these has a differential pair for input / can take balanced drive natively, and has a low Zout?

My ambition outweighed my talent ...... again

 

[codyt]

Tell us more...

 

[Zen Mod]

In time

 

[Vunce]

Nice!!

 

[andynor]

Yes yes, I have been waiting a long time for the eighth BJ.

 

[Zen Mod]

outweighed my talent

few more, from next day

 

[Zen Mod]

few more

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

 

[codyt]

Lookin good! I’ll add to post #1 soon

 

[Zen Mod]

do not, until there is actual thread

this was just for fun and tease

Great!
Is it a planned diy-shop product?

 

[Zen Mod]

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

 

[Zen Mod]

finally found time for this one, loooooooooooong time cooking

funny - found the other day scan of drawing - I did made my own pcbs for OS 35 yrs ago, from schmtc I took from original amp

go figure ..... that amp is old

 

[Jacruzer787]

MF? More fun….. Must Finish….Muy Fino….Mother…..

 

[Zen Mod]

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

 

[JeyDee]

Could be fun! 🙂👍

 

[Jacruzer787]

my love from youth...... and I still have one

Some would say you have a nostalgia problem!

MFMF A1 < Must Finish Music Fidelity A1 35 years later!

 

[Zen Mod]

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

 

[andynor]

There are no mistakes in MZM-land, only beauty.
