Marantz 2220B Repair 1 - Weak Output Channel

Repairing the weak output channel of amplifier by using the right tools can be helpful. In this video, I am sharing how to troubleshoot a weak channel for a Marantz 2220B receiver . The procedure in this video can be also applied to other receivers and amplifiers. Next video Part 2 will show the outcome after I replace the balance control and the other issue of this unit.

I have a similar problem with my Marantz 2226 where left channel output is way lower than right channel. Will try cleaning the balance fader and maybe replace it. Thank you for a detailed video.
