ZenerDiode Aleph4 and IRF9610

[Smithers]

Hi,

i am building my Aleph 4 and i wonder if it`s necessary to match the 9V1 Zenerdiodes, because the tolerance is 10%!

Do i only have to match the two IRF9610 at the input or do all three have to be matched?

Thanks in advance!

No!

Yes, you only need to match the mosfets marked Q1A1 and Q1A2 in the Aleph 4 service manual.
