Q. How to check specker impedance.
A. Use a signal generator, to generate a 1KHz signal put the speaker and
   a one ohm resistance in series, and connect the speaker-resistance
   combinations to the signal generator. Measure, the voltage across the
   speacker and the one ohm resistor. Now you can calculate the speaker's
   resistance at 1KHz.  Also check the DC resistance of the speaker with
   ohm-metar.  Your future speackers should have the same impedances.
Q. What could have gone wrong?
A. The output transformer that connects the speakers to Amp. might have
   shorted itself.  If so, it should be changed.  Look at the resistors
   see if you can find burning sign on those.  See if the Amp burns the
   fuse without speakers?  Also, tube Amp are not supposed to run with
   Sq. waves or very high frequencies.

Good luck, let me know if you had more problems.

                With highest regards,
