A electrical component's "resistance" is the measure of how hard it is for direct current (DC) to flow thru it. "Impedance" is the component's resistance when passing an alternating current (AC) thru it. The higher the impedance, the harder the amp has to work. So, 4 ohm speakers are easier to drive than 8 ohm speakers.

But at the same time the amp will sink more current...which is heat...which frys the driver stage of the amplifier.
ALSO, max power is achieved when the source (amp) and speakers have matched impedances. Otherwise you might be dissipating more of the power as waste heat in the amplifier and not in the speakers. This again leads to a cooked amplifier.

Four posts are for biwiring not four speakers.
Likely to be output stage thats toast from too low load at high output currents.
As said, parallel connection means harder load for amp. Not good.
Unless you had a Quad 303, then all would have been swell as would have self limited output

There are 8 posts on the Alpha 5, also a switch to switch between each set of speakers.
I've had the amp apart and can't see any obvious signs of damage, no black areas or even signs of a hot spot!!!

Very few speakers have been anything other than 6 - 8 Ohms for for many years. 8 Ohms is an easier load on an amplifier than 6 or 4. Some panel speakers are 2 Ohm, almost acting like a short circuit on an amplifier.
Look for speakers with a high efficiency rating
1 watt of noise should generate around 87 to 91 db in a well designed speaker. 86db requires the amp turning up to make the music as loud as an 89db speaker and so on. The amp has to work harder.
the average home system only uses about 5 to 9 watts to annoy the neighbours.
I could go on with proper figures if you want? Need to find my books though.
