DeForest D607 phono problem
6/16/2013 12:05:47 PMJ-F
Hello,

I am restoring this radio for a friend. The AM radio is working great, the turntable is now turning correctly, but no sound into the speaker when using turntable. I can ear sound coming out from the arm (cartridge), but with my scope and can't see anything form the output. Is there any way to repair or replace the cartridge or arm? Look to be: Shure P93 78 rpm crystal phono cartridge.

Thank you!

If you touch the hot wire from the cartridge with your finger or screwdriver and hear loud hum with the volume up, chances are the crystal has given it up in the cartridge. They are very sensitive to heat and humidity, so they never lasted very long. West-Tech may be able to repair it.
