Zenith 6D512

This is a chassis only restoration of a Zenith 6D512 AM SW radio.  Lots of deteriorated insulation.  This is unfortunately common on some radio during the WWII era.  This radio was manufactured "pre April 1941".  This radio was probably sitting on a table playing music until shocking and tragic new blared out of the speaker on December 7, 1941.

It should be less expensive to send this speaker for re-coning as compared to me  fabricating a mount accommodating a modern speaker.  I have an estimate coming.

Speaker removed for shipping to re-coner.

You cant hear it but it sounds good!

Metal tube on right Converter is a bit weak.  The radio works fine but a strong converter may increase sensistivity.

Open strap to connect an Antenna to one screw and a ground to the other.  Swap for best reception.
