Cleaning 2600A speaker relay

[navela78]

I am not an electrical/electronics engieering and have not done any soldering before.

i acquired a NAD 2600A recently and it sounds great except at lower volumes the channels are cutting off. I looked around in the forum and found that the speaker relay needs to be cleaned or replaced. I am trying to clean it instead of replacing because I do not mess with soldering.

I found this nice video
YouTube

In about 5:37 in that video the guy shows the top of the original relay open. How did he do that? Is it possible to open the top of the relay without taking it off the PCB?

Any help greatly appreciated!

If the sound cuts off at low levels, then the contacts are consumed.
It is better to replace the relay.
With one, which has 2 or more contacts.

If you haven´t done any soldering, then begin with testing setup.
Buy a soldering iron in the next electronics shop.

Thanks Keruskerfuerst. I will start learning soldering. In the meantime ... is it possible to open the top of the relay?

Even if you succed in opening it, you will never get it in the condition `as new`. The relays are not made to be `repaired`. You will have to buy a new one to make the job right.

Can you post a picture of the relay?

Is it possible to open the top of the relay?

But then dust will fall into the relay.

You really have to replace the relay.
In my experience, cleaning the relay contacts will never give good results and is a waste of time.
