[TenTec] Relay for Corsair, argosy

[Tod Glenn]

Greetings all.

I'd like to be able to use the AF power switch on my Corsair and  
Argosy with my Astron PS.  TenTec states that the AF switch is not  
rated to use 12v at the required amperage.  They recommend using a  
relay, Guardian series 200 or Potter Brumfield PR3DYO.  Neither seems  
readily available.  Can anyone recommend a suitable replacement?

Thanks.
