One should consider the power supply rails. I've seen vintage gear rated at 50, 60 and 70 watts all have +- 50v rails. A sine wave without rail sag will produce 155W RMS. That will also be the peak music power. If music has 10db peaks most of the music signal will drive the amp to 15-20watts.
I have a 1980 amp with meters. On dynamic material the meters read 20 watts or so but the clip lights are flashing and a scope on the outputs shows the +- 60 volt peaks. The system is playing very loud then.
