Default Quad 66 PreAmp aux power

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.




Look in the surplus market and get a solid-state relay. They usually work of
6-48Vdc and will switch 30A or more. They use triacs as the active component
and switch at the xero crossing of the mains so they are safe to use to feed
a transformer.
