I have started the restoration of my KS490WE.  I am not an electronics technician and his is my first  restoration project. While investigating a "buzzing" sound I discovered that the foam surrounds for one of the bass drivers had disintegrated.   The other speakers appear and sound fine.  The questions I have are:

1.  Is it possible to get a replacement (original speaker) for one or both of the bass drivers?  If so, where?

2. If an original replacement is not available, what is a good substitute?  What specifications (5 ohm resistance, what else)?

3.  Would "refoaming" the bass drivers be a better option? NB: They are several options for this here in the US including private companies.

All suggestions will be appreciated.

Hello All:

I am new to this community but I am a great fan of vintage Grundig consoles from the '50's and '60's.  I currently have two beautiful specimens (SO162US and KS490WE) and am considering a third (SO190US).  I am not a skilled technician but have found a wonderful old retired technician who will update them for me.  The SO162US plays and sounds pretty good but I am looking for a part or a part template for my KS490WE.  When the FM band button is depressed on the receiver it rotates a little metal cam which engages the FM clutch* to the tuning flywheel.  On my KS490 that little cam has disintegrated.  It needs to be replaced or, if some one has a manufacturing drawing, I could make one or have one made.  I suspect that this part is very similar across all Grunding receiver chassis and may have to by a junk one to scrap.  Anyone have any leads or other thoughts?

*And disengages the LW/SW1/SW2/BC clutch.
