You must make 11 individual preamps (10 channels, 1 master) for mono mixer, or double for stereo.

apex,
can 10 channel mono input have stereo main/master

is this a panoramic pots?
10k balance
50k L/R master out?

No, you can mix mono and stereo channels with this circuit

 

[apexaudio]

Panorama pot (50k) in MX1 was replaced with two 22k resistor on mono input.

hI APEX,

What is the actual size/dimension of the pcb and by any chance the replacement part for the output transistor?

Thanks and regards

PCB size: 260x95mm, you can use any darlington pair BDW83D/BDW84D... or TO3 MJ11015/MJ11016...

 

[apexaudio]

TIP142/TIP147 also can be used
