Stereo Amplifier channel balance test

Hi All

I am following a bloke on Youtube and he posted this Amp channel balance test
I have a old Marantz 2238 receiver and 2 Sansui amps, it seems sometimes that one channel is slightly louder
than the other on the Marantz, was wondering if it would be a good idea to try he's test

Very interesting

 

Hi All

I did end up given this ago, I used a mp3 player for a 1khz tone I found.
Did test with just mp3 player connected to Audacity then with all 3 amps and 2 were low on one channel, Marantz was the worse.
Will now look to see if I can get the receiver serviced
