Wonder if it possible to change som values to make som more gain in this curcuit.
As it is now it’s +/-5db @ 50Hz and 10kHz. I would like it to be more gain (+8db?), especially in the bass and perhaps move the frequency up to 65-80hz.
And yes i know most lf the time flat or tone defeat is preferred but this is for my workroom and i just want some more punch/bass when i’m listening rock n pop (not any real hifi setup here)
It’s a NAD C162 preamp and i think many Nad share same topology so may it can help someone else too.
Best regards
Johan

Here's a circuit that has both much more loss and boost range.
You may be able to change your board to this version.
It uses the same value of pots, but needs a larger input capacitor.
A quality tone control circuit using opamp and few passive components

There is no gain. Only loss. You can't get gain out of a passive circuit. You need active elements for gain. The 36K resistor appears to be in the wrong place, but if you want gain you should throw this out and use a Baxandall circuit with an active gain element at the output side.

- Bass/ Treble curcuit. More gain?
