Dad found this amongst all his random tat.

JPS SC100 - 100 watt slave power amp,

Anyone got any info? more to the point is it worth anything or is it destined for the skip?

Something old, generic and probably fairly well-made and reliable. It's big, looks heavy and will no doubt contain a big transformer and discrete components. From the size of it it's likely to be a genuine 100W.

If it works it's useful as a power amp or a backup amp. Probably worth no more than about £50, but I wouldn't throw it away.

Cheers @ICBM,

seem to remember it was in a box with an old HH amplifier, which got sold.

if its just a power amp, could it be used to power speakers for Helix?

Yes.

The question is whether it's in good working order - with something of this age, leaking/failed filter caps are quite likely. Probably worth a look inside before you power it up - I should have mentioned that before really!

No worries , taking it apart for a nose/check was first on my list

Just be a little bit careful when opening it up, even though it is SS, there could still be +/- 75volts in there, with very large power supply filter caps - certainly enough to blow the end off a screwdriver
