Good day and happy New Year's Eve parties ... Please, I need the diagram of a Kenwood amplifier model MA300, it only has audio in one channel, it brings 2 transistors per channel, (N407718, N407925) and there are 6 channels, I followed the signal and only reaches a channel, there are voltages in the Trs. Outbound; I just need to locate the voltage, power lines and track the audio of the preamps, please, thank you ...
