Rather as I suspected - a 'real' lightning strike. You don't seriously believe that a 'surge suppressor' (of the type were talking about) would have prevented any of that damage, do you?
Kind Regards, John
There is enough stray capacitive effect in mains network and domestic wiring to quench the majority of voltage spikes created outside the house.
If some electrical item in the house is creating voltage spikes on the mains then it is best practise to quench the spikes at source.
As John said lighting strike is very different and a "surge suppressor" on the mains will not protect the equipment. Often the damage is due to the local ground potential rising a few hundred ( even thousand ) volts above normal and creating massive ( but very short lived ) currents in cables ( such as telephone service ) that run to areas where ground potential was not lifted by the lightning strike.
A ground strike landed about 100 yards from a Fire Station which also had a Fire Service radio station in the building. A few minutes later the control room ( 15 miles away ) got an automatic "Paging TX Fault" alarm. On arrival the engineer found the only fault was in the telephone circuit in the modem where the isolation transformer was visibly scorched. Every other item of equipment in the radio room was OK. Later it was found that some of the the telephone equipment on the direct lines to the control room had also suffered minor damage.

I contacted a person in real life whom I didn't want to bother with such a trivial issue and he said that unless fitting a UPS it wasn't worth it, that it indeed was a marketing scam.
It's a bit of a shock for me.

So, you didn't want to believe our input.
Aah well
Even Winston came up with the correct guidance

If ever you are seated and feeling fortified, go and look at Russ Andrew's website.
£100 for a mains lead and £2,000 for a speaker cable
Do they still claim that there is such a thing as "directional cable"?
(edit: oh yes, yes, they do...)
