Could a Crate BV120H valve amp really blow 4x 12 inch 16 ohm speaker box ?
Amp as received was set for 16 ohm output, I measured the speaker box
impedance at 13 ohm, or so, before connecting up just to be sure.
Very feeble and distorted sound. No signs of the reported burning smell,
output matching transformer primaries at about 50 ohm seemed ok and
secondaries not open circuit in the amp so turned to the speakers. The amp
o/p switch setting was set for 4 ohms instead of 16 ohms but as I measured
16 ohms I assumed a switch problem.

It sounds like the speakers were blown before this exercise
started... what you did (with no loud noise) should not have
blown any speakers... *maybe* the amp could suffer, but
not the speakers.
