Modern tube amps from known reliable US/Euro/Japanese tube manufacturers are pretty rock solid. Add in modern auto-bias and protection circuity (which is truly wonderful), and it's even better. You have to replace tubes periodically, but when you factor in speaker safety I'm starting to feel like I trust tube amps MORE than solid state. A lot of the concern voiced about tube amp reliability is simply speculation, or based on poor choices (that $500 tube amp from amazon or aliexpress).
    You are correct pure Tube Amps seem to slide under the radar when it comes to DC destruction of Speakers /etc.

    in my 70 years owning Gears the only "tubes installed Amp" I had that destroyed Speaker Drivers was a Brand new just unpacked Counterpoint

    Pre and Hybrid Power Amp Combo which proceeded to smoke out the room with unabashed fury taking outa pair of Spender BC1's.

    The only other time was mid 70's Amcron 150 Pre and Power dittoed a new pair of JBL Jubal L65's in a mini Chernobyl !

    I definitely recommend avoidance of the Pre + Amp brands mentioned above for the sake of your sanity and wallet

    End of Rant

    Respectfully, what does that have to do with my comment above from any practical (i.e., real world) perspective?

    Also, with respect to your comment about the BOM, where is the data that supports this statement?
