I am using a Stavol, a couple of months ago, there was a spike, my tube amp just hiccuped and continued playing.
But my Samsung LCD TV, which is off at the time, but plugged on another Stavol, got busted power supply board (it is quite expensive to replace). I think the servo type is too slow for the Samsung.
Thanks.

what you needed there was a line conditioner, you can buy these MOV's from raon, costs less than a 100 per piece, get one rated for 250 or 260 volts and wire up 4 or 6 in parallel, make sure it is installed after the fuse.
you can install them inside the stavol after the fuse, size is as small as a disk ceramic cap....
these will protect your equipment from voltage spikes...
BUT not effective in stopping high current surges or sustained over voltages.

The thing to do here is to install them after the fuse, say you have those mov's rated at 250volts, what they will do is blow the fuse in case of sustained overvoltage, for example a 110volt equipment accidentally pluged into 220volts, thus preventing extensive damage to your equipment. Otherwise, for transients lasting a few cycles they will absorb the energy, that is why having several in parallel makes for greater absorbing capacity.

Thank you all for your inputs. The servo type seems to be more expensive when I looked around compared to the relay type. Is there any reason for this?
Thanks,

Tony,
Found some MOVs at RS, 240V at 1750A, would this be ok? Thanks.

i would get someting a bit higher say 250, but i guess if your line does not exceed 230 then that would be fine...three or four of those would even better.
