Question about Yamaha P2500S Amplifier
This explains that your output of the side A is not working and it is possible that the output driver would have failed. First of all open the set and check on the fuses. Use a good multimeter to check for the + B voltage in the output drivers. If absent check the power line for break or burn out. If ok then check on the fusible resistors that give the biasing to the drivers. replace if they are Ok but be careful as ther may be high voltages in this section tthat might damage the circuit if shorted. if you find the outputs draing in more or less then it must be checked after removal. It is easier to confirm as you have a working side and so replace from the working side or test voltage onthe B side as a comparison to confirm. I hope you try this out. Good day
