Hi All,

I would like to ask you for a advice how to add a eq to an 6n13s amp from the schematic.

My question is, what do you think will be the best way to make this eq working with this amp?
The easiest way will be to just add it in front, but maybe it is worth puting it between V1/1 and V1/2 ? Then maybe swap the 12AX7 with 6N8S to make it easier.

I would apreciate If someone more experiened could share his thoughts about this idea.

The power amp has overall NFB. EQ inside the loop will have hardly any effect due to NFB action.

Yes, put your EQ circuit in front of your power amp circuit. Look at "any" old integrated amp; that's how it is done.

(It is possible to work tone controls into the NFB. This is usually a cost-cutting commercial compromise.)
