I'm not sure how a tube preamp hooked to a SS amp can take out your speakers, but I guess anything is possible…it would seem that the preamp just stops working when a tube blows, and isn't likely to dump anything beyond (maybe) some noise into the amp which I suppose could stress the speakers…still…hmm...
Do blown preamp tubes cause other issues?
As a relatively tube newbie I'd like to know if one of the preamp tubes blew while listening at loud levels using a solid state amp would there be the potential to damage the unit itself plus the amplifier and thus the speakers? I have ARC Ref 5 or 6 in mind. I don't ever seem to hear this discussed. Thanks for any info provided.
