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!

Stop playing around and just replace those relays.

I had a 1980's era pro amplifier with output relays.  Replaced them and noticed the contacts on modern relays were much better.  Instead of being a ball on a flat surface they were hemi-spherical matching surfaces so the contact area was much larger with the replacements.

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). 

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.
