Hi All,

I am planning to build the Aleph 5, and of course, have some questions.
In the Aleph 5 and 4, there is a slight difference on the original Component Layouts from one channel to other, i.e. R1, Z9(Aleph 4) and R13, Z5(Aleph 5) in the left side channels are unpaired. Simply no exist. Why?
Are the resistor R21(Aleph 5), have different value on right channel, like R29(619 ohm and 523 ohm) in the Aleph4.
If does, which value?
After all, i'm interested in Aleph 5 Left and Right(if exist) Channel schematic without various ambiguities.
Can anyone send me a copy?

Many thanks in advance,


nenadH
