Amplifier Output Relays


Hi Goner’s,

Well after way too much time and money in parts and labor, my tech tapped on the right channel relay and discovered the reason for why the right speaker kept cutting out. So he cleaned off the corrosion and sprayed it with Deoxit and it came back. I was gratefully playing the stereo for a few hours when I decided to play the Ayre test CD ‘Irrational but Efficacious’ full glide tone and heard the two speakers drop out for a second and then experienced cutting in and out of the left channel. It’s strange to me that this full glide tone could trigger an issue but that seems to be the case. Anyway, the relays that I need to order are modified for direct inputs. I play strictly through the direct rca’s rather than CD 1, Phono, etc…The technician wants to exhaust all possibilities that the relays can be salvaged but he is overestimating the amount of work involved in changing them. The parts for both sides is a total of 60 euros so I plan on ordering them soon. Any advice from people who are familiar with this headache?
Thanks!

Happy Holidays!

As far as the Amplimo, I know this isn’t the relay that needs replacing. I can make mention of it to the manufacturer. Maybe someone could explain the Amplino loudspeaker relays? The parts are ALE2X302 output relays.

Erik, these aren’t that old, there still being used today. Anyway, no kidding but I’ve got to convince my tech to do this at my home. The task should take ten minutes to get to but he’s saying the PCB needs to removed (it doesn’t) and this behemoth needs to go to his shop (it shouldn’t). 

I'm assuming that once the relays are exchanged that operations will go back to normal.

imhififan, thank you for sharing your knowledgeable insight tower I'm not sure a different relay would be applicable. AS I said, I will make mention of it but ultimately I need to follow the advise of the manufacturer.

I also com to realize that a direct modified relay has nothing to do with using Direct RCA inputs so please disregard my previous statement as such. As for what direct modified relays are, I'm still not sure.

I've been In contact with the manufacturer who's been nothing short of amazing since the issue started with the right channel. His comment is that the right channel issue was with the output relay. The issue with the left channel started shortly after the tech cleaned the right relay and got it working again. I will check the headphones since that is a separate relay altogether. I then will try other inputs. Once I check these, then I'll post my findings.

Yeah, according to the manufacturer, the headphones use a separate relay. His instructions are the same; tap the relay to see if the tone changes, try the headphones and try different inputs.

Also, my tech found two bad solder joints and a loose wire and fixed those many months ago when I initially started having problems. When he found the relay was reacting to his tapping on it, he checked those solder joints and they were good. When the cutting out in the left channel started a couple of days ago, I couldn’t understand why he didn’t do the same to the left relay as he did to the right but that really doesn’t matter at this point. Yes, the relays are the same age. They are the original parts.

imhififan,

I played the amp today while listening through headphones and it played flawlessly. Pretty much what I was hoping for.
