re: SX-408

I have just finished cleaning all the pots on my SX-408 and now my left channel doesn't work :(

I'm not good at reading schematics but I can replace circuitry if needed, does any one know where I should start?

re: SX-408

Always start with fuses.Check and If necessary-replace them. Then you have two identical amplifiers-for left and right channels.If the right works-it will be your benchmark.Now-step by step you can compare voltages between the same points of
the left and right channel.Right works-this means all voltages are OK.The reason is a circuit in left one.Find it by measuring the voltages, and when you find a different voltage-somewhere around is your problem.
Hope come in handy.
