I changed a variable resistor of the equalizer that went bad for another with a close value and I've had it using it for several years, after doing this one channel worked a little lower, but today I let the audio of one channel come out from the amplifier. It is not cable or speakers and even if I turn off the equalizer, the audio from one channel of the amplifier no longer comes out. Please how can I repair this.

Hello!
Connect a function generator/sound generator to one input of the amplifier and drive it with a 1kHz/0.7Vpp sine/square signal. You can see where the error is by measuring the stages with an oscilloscope. Good luck with the repair.
