Coupling Bosoz to Aleph cap question?

protos · 12th December 2002, 12:12 PM

Since the Aleph has input coupling caps do we absolutely need the output coupling caps of BOSOZ? It could mean one cap less on each signal line.

Hello protos,

The Alephs don't have input capacitors.

Can you be more specific about where do you see the
input coupling capacitors on the Aleph amplifiers ?

Best regards,

For instance in Aleph 5 where C5 is decoupling for the neg input. Goes for many of the Alephs including A30 and A60.

Yes, it's usually 220uf and at the neg input. I had the impression there was one at the pos as well . Is this a coupling cap and why is it only on one input?

protos,

it´s on one input but at the same time in the feedback loop and sees to it that dc is not ampilfied.
