I am anxious not to burn out the relay that switches power to other
equipment by loading it with a valve power amp. Can anyone recommend the
source of a mains contactor that will switch on and off a few amperes
whilst drawing only minimal current? UK based so 230v working required.

Perhaps the most 'standard' power relay is an octal plug in type. They
have DPDT contacts rated at 10 amps, and the coil operating current is
very low - under 10mA. A base with screw terminals is also available.

Relay JG60 3.99, base JG54 1.99.

Or just about any electronics supplier, RS, CPC, Rapid etc.

A decent electrical wholesaler might even stock them too.

TLC do, if there's a branch near you.
