[DIY] OT: Tube amp disaster

[Tony Allgood]

Hi all,

Is it possible to destroy a tube amp by running it at the wrong output
impedance? I have just got an amp that was run with a 8 ohm speaker in
its four ohm output socket for about a week. Then it started to smell
bad and started to oscillate. When I turned it on, after connecting the
output correctly, it then started to smoke. I haven't turned it on
again.

BTW: It's the same Crate BV-60 that I looked at several weeks ago so its
probably another crappy fault that has developed due to the board
warping as it gets hot.
