    assume you have checked the right speaker cable and amp connection?

    Speaker channels

    I have checked both speakers and renewed speaker cable incase there was a break. As I said if I put either speaker on the left channel then both speakers will work, it does appear that the right channel is down for whatever reason
    Thanks Doug:(

    Hi Doug, Diagnosing the problem with your amp will likely require tracing the signal from the pre-amp to the outputs with an oscilloscope. Do you have one?

    Specific advice is not necessarily possible here. Quite often with amplifiers the output transistors (The larger ones on the heatsink) fail but also take out other components around them that mean replacing the transistors alone may cause them to fail again.

    If you are really determined to fix this yourself then I would recommend looking up generic amplifier repair guides and finding your amp's service manual would be helpful too.
