Amplimo LR-24 relays - source?

I'm trying to find some reasonably reliable relays (DPST) to use as speaker output switching relays. Previously used Omron 2Gs oxidised their contacts and sounded horrible. I came across the Amplimo LR24 which has dual tungsten and gold contacts (the tungsten closing first). The snag is I cannot seem to source one in the UK (Amplimo won't supply to UK due to Brexit). Does anyone know of a source or any good alternative?

(Next tine round clearly a design which doesn't need speaker relays would be good - or a shorting relay rather than a signal carryting one)
