Title: Becker buzz.....
Post by: dldubois on October 30, 2023, 16:41:33

I've got the original Becker cassette and amp in my car and I've got a background buzz that I just can't seem to shake.   Any thoughts on testing the noise suppression that I should have OR where to input to better address with aftermarket?   Super annoying.

I've got the same issue, even when the engine isn't running.  sent it back to Becker, worked for a while and then came back. I have the 71 stereo unit with the separate amp.

Hello, if it buzzes when the engine isn't running, perhaps check the earth/ground connections at the radio, amp and aerial, and the connections between them.  Could also be a damaged or bad speaker

Depends where the buzz is coming from

If it only buzzes when the engine is running, then check the above, but could then also be a bad suppression component, could be a long job checking or replacing all of those, there are details in the tech manual under radios/suppression

Try taking a grounding wire and attach one end to the radio Chassie and the other end to an existing ground source.
