This is a Grundig 3089PH with a Perpentuum-Ebner 4320 turn table with mono crystal cartridge.  This unit is receiving a total overhaul restoration.  

The finish was pealing, dried and flaking.  The turn table needs significant restoration and conversion from 50 Hz to 60 Hz line frequency.  And of course the chassis needed the standard restorative efforts.  The owner has a new dial glass awaiting the return of this radio.  It seems like this chassis configuration with the dial glass pressing on the wood frame is subject to breakage. 

Most of these pictures are a record of how the unit is to be reassembled.  It is great having a digital camera.  You can take many pictures at $0.00 cost and save a bundle in mistakes!

This restoration is all but done.  I am seeking out a new idler wheel for the phono and a platter mat is on order.
