Question about Audio Players & Recorders
First of all , the fault of a unequal volume levels is a fault to be looked in with some expertise. This is because of the fact that there is no failure but a difference in gain in some stages. If you have crossed over the speakers and confirmed that the fault is definitly in the amplifier. Now you will need to check first with a multimeter for diffferent bias in the preamp and power amp stages. If you have evidencce of a difference cross check to confirm. Next apply an audio signal from an injector and test from the preamp to the power amp. The section where the gain was noticed must be looked into and the gain corrected by checking variation of resistor/ capacitor values. You will need to replace fromt he working side- crossing the good part- to confirm the part before you buy and replace. Try this out but do it with caution when the circuit is powered , attempt only if confident and familiar with circuits. Hope I could help. Good day
