Only thing I would wish for was maybe an ohm selector on
the secondary output.
I assume the secondary out switches off the internal 10" speaker ??

Yeah I never understood why amps would have an output for a cab but no ohm selector.

That's one thing I love about Boogies...you never have to worry about that, they're impervious to mis-matches. They actually encourage you to try mis-matched cabs for different tones...

How is THAT possible?

You mean I can run two cabs fulla 16ohm celestions, wire em all parallel to become a single 2 ohm load and the output transformer will not fail?

That's not only impossible, it's as foolish a claim as it is bold. Thermal breakdown from the resistance alone, heating it up, would cause the polyester coating on the inside trans coils to melt and short out.

Link that badassed claim, I wanna see it in text form.. or were you just told this bullshit by somebody? Because that is a buncha bullshit right there.

You can, and will, harm the output trannys permanently on a below-impedanced mismatch of output loads on anything, eventually.

Do not do this to any equipment you expect to enjoy for very long.

But is Jay referring to Mesa cabs only, or all brands ?
The Boogers may have impedance matching built in ?

(You would probably know if that was the case, Gar ?)

I've seen many power amps that rate outputs from
2-16 ohm... (Without having to switch anything)
