Re: [MBZ] Fun With Beckers

Possibly.  Typically it’s the encoder that’s bad. I’ve had some luck with 
spritzing them with contact cleaner, but for the most part when they exhibit 
this kind of behavior they’re on the way out.

So when you turn the knob in the newer radios and the volume 
bounces up and down with each click or even when you turn the 
knob really fast, is it always the encoder that is bad or could 
it also be just the little switch that sends the pulses?

So I guess you’ll need to tear a later model Becker apart to get a part number.

No, unless you locate a source for the digital encoder they use.  I know a guy 
that replaces them for something like $60 if you send him the whole faceplate.  
I’ll ask him if he can give me the part number and a source.

Got any decent knobs?  Looks like they are mistaking them for being gold plated 
on eBay and elsewhere.  $25 for one of them.  Yikes!

I have the part number from Mercedes, but I’m betting they’re NLA.  I’ll find 
out Monday.

Have you seen any sort of fix for the volume knob issue other that sending it 
in to get the radio rebuilt?

[MBZ] Fun With Beckers

[Dan Penoff via Mercedes]

I really wanted to get the original Becker back in my wagon, so I put a WTB 
thread up on Benzworld.

Got a response from a guy in Louisiana who had two of them, condition unknown.  
I paid shipping ($15) and he sent me the pair. One was sort of ratty and had a 
loose “Seek” button, the other looked pretty nice.

Got the codes from the radio code website in Lithuania and powered both up OK.  
The nicer one didn’t want to recognize my CD changer for some reason.  The 
rattier one did, but it has a really rough volume knob and the typical “turn 
the knob and guess where the volume will end up?” issue.

So I started to tinker…

After about 10 minutes of work, I swapped the good faceplate from the nice unit 
onto the radio that played nice with the CD changer.  I also noticed that the 
volume control on this faceplate had been updated with the newer stepper 
switch, so it will never develop the volume control issue.  I cleaned the tape 
mechanism - on this radio it looks as if it’s never been used.  Capstans and 
rollers were clean, as was the head.

So now I’ve got a fully functional BE 1692 with a CD changer in my 98 E320 
wagon.  While it doesn’t sound *quite* as nice as the aftermarket head unit 
that had a display that looked like Jimi Hendrix threw up on it, it works great 
and all the features are functional.  I just need to find a new volume knob for 
it as both of them were kind of ratty.
