    Please let me know if this is helping..
    could be wiring is wrong..

    Interesting history here, it says they were often used in an active setup driving HF/LF on one channel, I wonder if that is achieved with the mono button or an external/internal switch/link.

    I don't know the Nytech circuit so could be talking rubbish but it looks to me like there's a fault at the mono/stereo switch (if there is one). Both channels seem to be working and appear to be being summed. That's going to happen after a gain/buffer stage I'd suspect. If I'm correct and there's a tape out then that might still be working in stereo if you can try it? If not it takes the fault to even earlier in the circuit.

    Either its been hard wired for mono - might have been done many moons ago - or it might be a failed mono switch or shorted pin on it. It should be easy to check if you can get it open. At least both channels are working!
