NFB loop on Mesa Express?

Post by jamme61 »

On the negative feedback loop how does the cap C39 (.005 Page 6) work? does it add highs or take them away? thanks for any help

C39 increases feedback of high frequencies, so it will reduce the high frequency content in the output.

Yes, and switching in or out the 22k you'll change the amount and the frequency of the rolll off.
