Ameritron AL-1500 Relay

Riki, K7NJ All Messages By This Member #41031 The output relay in my Ameritron AL-1500 needs to be changed. I checked with MFJ since they are still selling some Ameritron replacement parts, but no luck.? From the user manual, this is "RLY1" and its Ameritron part number is 408-6139. ? This is a 3PDT, 10A, 12V DC through hole PCB mount relay. Two of the poles are used for RF switching and the third is used for another function. I've searched on Mouser, Digikey, Allied, Newark and E-bay websites without finding anything that might be a satisfactory replacement. ? Ideally, an original replacement part would be found. This would allay my concern about the contact materials which should be gold or gold plated for the two NC RF contacts to ensure good contact when receiving.? ? Suggestions would be appreciated. ? 73 de Riki K7NJ? ?

Louis Parascondola All Messages By This Member #41033 The AL1500 relay is a typical 3pdt 12v relay. ?There is nothing magical about it. ?There are many relays that can be subsidized for it if the original cannot be found. ?With Ameritron going out of business and parts supply drying up us hams are going to have to rely on our instincts to improvise to keep our gear working. ?Is the coil open on your relay? ?What seems to be the problem that not must be replaced? toggle quoted message Show quoted text On Sunday, February 23, 2025, 9:29 PM, DupyRail via groups.io <andytron434@...> wrote: Try w8JI, CTR Engineering, he may have one. 73?

Elijah All Messages By This Member #41034 I had a bad relay on my Al-811H and went this route. There’s a write up on DX World here: ? I bought special teflon coated wire because of the heat in this area per the recommendations in the article.?
