Output test on amp


Is there a way to test frequency response vs dB output with a test record and multimeter?

im trying to determine if both channels are outputting all frequencies at equal outputs. 
If not is there another way to achieve this at home.

I have a 30 year old ARC CL 60 that appears to be a few decibels down in the higher frequencies in the right channel.  But it’s subtle; so I’m not 100% sure. 
I have eliminated all of he other variables including,  it not limited to, cables, tubes, flip flopping speakers - and tubes and sources. So I figured I do an empirical test before sending it in.
