Teac 2A mixer circuit diagram

[Andronico]

Hi, my name is Julian and have a friend that has an old Teac 2A mixer. It has six channels and the first two don't work at all. Have anybody a circuit diagram or web link for this model in order to try to repair it ?
Thanks in advance.

I dont know how this particular mixer is set up.. but i bought an old mixer a while back with only 2 out of 12 channels working and i opened it up to find each channel had its own PCB with bus bars connecting them all together, turns out the solder joints on the bus bars were bad, resoldered them all and it works perfectly now. I'd say rip it open and have a good look around, you may not even need a circuit diagram.. then again im not familiar with this particular mixer.. so you may need a circuit diagram in order to trace the fault..

Thank you Owen, I'll talk to my friend to open the mixer, the idea to obtain a circuit was that he teachs guitar and uses the mixer the most part of the day but I'll try looking into. Thanks again and excuse my bad english

As long as at least one channel's working properly, it should be quite easy to troubleshoot the others by comparing voltages and signal levels.
