    Hi, excuse me if i ve posted that in the wrong place.
    I ve uploaded a shematic of an eprom programmer power supply that i want to build ,as you can see this power supply uses two relays, relay1 in green ,and relay2 in red.the guy who build this power supply says that the two relays have to be coil relay 24v 4rt with 1300ohms of resistance.my question can i put any other relay than the one given cause i could nt find on ebay
    the same one or maybe can someone help me with that thanks very much.
    this is the whole project ,sorry t s in french.
