Extremely low volume on old receiver

Vintage Asylum

Classic gear from yesteryear; vintage audio standing the test of time.

I have a Pioneer SX-580 receiver with extremely low output level. Have to peg the volume knob to barely get background level. Even with headphones have to turn it up all the way to barely hear it. Quality of Tthe sound seems ok, if weak in the bass. here is equal output on both channels. All controls and functions operate normally. Problem occurs on aux input as well as built-in tuner. It's just as if the amp section stopped working.

Problem began suddenly and the first few times only occurred when I first turned it on and then after 5-10 minutes normal volume would kick in and sound just fine. But is all the time now.

What would go bad and take out both amp channels without affecting anything else?
