Involve CD4....Is there any life in it????

Chucky, that is NOT Lou's schematic. It's a link to JVC 4DD-5 ( a very harsh entry level demodulator vastly inexpensive and easily available on fleabay).

Hey Chucky,
Any progress on the CD-4 demodulator ?. This is your first post in over 2 years. Hope everything is going fine.

The JVC 4DD-5 appears to meet Hi Fi standards for low distortion and low noise.

AFAIK, the Marantz CD-400 is a JVC 4DD-5 clone.


I'm trying to find a way to use existing hardware CD-4 Decoder designs
(with some hardware updates) to simplify the creation of a new
(hopefully not to expensive) hardware CD-4 Decoder.
