TB-3 tone controls are fabulous!
I'm correcting the overall rising speaker response of small midbass driver. I'll try it with a pass full range eq. This driver still need cone break up attenuated!
My plan is to install it in an integrated amp along with Apex AX11 mini

Apex Mic, Line, EQ... Pré-amp https://www.diyaudio.com/community/threads/mic-line-eq-preamps.167363/
HI need some pcb for home use how can i conncet with youThanks guys, if anyone decides to order pcbs, let me know I will buy off a couple.
I'm using linear.Hi all,
referring to the REV3 scheme of #14,268 - I wanted to know about the 3 potentiometers (bass-mid-treble)
are they lin or log?
many thanks,
Marco.
This one fits. I would like to find other options for 10k linear that will fit the pcb

edit - BTW, the Bourns pot has a center detent. The response is basically flat at the detent. From my acoustic measurements it looks like
an approximate 6db cut and boost

Hi all,Apex BJT STEREO PRE-AMP SB 3.1 2014 - 2020
Hi guys I got this new layout I decide to go back a re-done the BJT pre-amp now that I have more experience I'm gonna posted here please if some one see an error let me know I just make it today I attached the schematic I use on simulation
Apex BJT STEREO PRE-AMP SB 3.1
Note: is not tested yet
In this preamp Apex SB 3.1 do the transistors have to be paired for a best result?
I think XRK made it and was satisfied.
A5 PcbIs it a black&white pcb for this simple amplifier?

Somehow, I never revisited this design till now.but difficult to layout..
So here is a version of it, after a long long time.
