THX Zen Mod,

I will occupy myself with the matter the next hours...

best for you

with a little shame the circuit

.... only hand corrected, I could not manage photoshop sufficiently......

The only thing that jumps out is R14. That should be 500 ohms to get 1 to 3 volts or so.
You can omit zeners Z1-4 if you want.

thanks Bill,

I omitted the Zener already and 500 Ohm is the value Aleph 5 has installed. I will try different values.
Highs and medium area are good, bass is less than with pure A3, maybe Mos-Fet bloom is away, I´ll build in a supplementary special produced for generg Bloom-Fet :::::::::::

Hi Bill,
sorry the 2SK170 are upside down, you are wright. Only in the schematic

, correct in the amplifier!

Zen Mod · 23rd November 2010, 01:45 PM

remove two anti-osci caps
add zenner across upper bjt
observe few resistor changes in neg input , also 220uF

vary circled resistors for your liking

use Paint for simple schm edit

ah, clamping the CCS for better recovery...

THX Zen Mod!

Bill Fuss · 23rd November 2010, 02:10 PM

Forgive me for asking, but what is limiting the current swing of the Aleph CS going to do to increase performance? Why don't you just disable the Aleph circuitry if you want it to clip earlier?

verrrry interesting,

lowering the R114 gives more bass, a sound more similar to F4 and less details coming from SSR100 I suppose.
I went to 350 Ohm, think I will go up a little bit.....

THX to Bill and Zen Mod

Paint is for sure the better choice, but I changed to Mac OS X......
