Help please anyone
I’ve completed a build of the 2017 PCB, everything is perfect except zero audio output from voice 3 (far right voice looking from the front). I’ve replaced almost everything, all the IC, the transistors etc, everything placed perfectly from what I can see. On the oscilloscope it shows a super high frequency well out of audio range of all the wave shapes although they are distorted a little, can’t trim at all. I’m absolutely stumped, voltages all good, the outputs of the TL074 show the same issue, very high frequency of all waves. Anyone had similar problems?
Many thanks
