low power tube amp

If the distortion from overdriven tube amps harmed speakers, angry electric guitar players would be everywhere instead of just here and there. My tube hifi amp is somewhere around 65 watts per side and seems to have plenty of headroom (the speakers are around 90 db efficiency). I grew up with tube guitar amps going back to the early 60s when I first fooled around with my cousin’s new ’61 blonde Fender Bandmaster. I eventually bought that amp from him to use for live stuff off and on for many years, and learned how damned loud 40 to 60 watts can be. What? Speak up…I can’t friggin’ hear you...
