Mingda mc34-a


Hello,
I have a Mingda mc34-a and I,m wondering if you have ever biased one of these amps. I have been told the bias pots are similar on these amps. The bias pots have two copper wires running into it and another coming in from underneath. Which wires do it use with my amp meter. Any help would be greatly appeciated.
Thanks,
Kyle
