CD4 decoder for Beogram 3400

24 replies

The very annoying thing is that I did have one of these but took it to Bellac. I never fitted it to the 3400 so it was in the original packaging. I told Steve he could sell it when Bellac was being sold so I imagine he did.

At least we know it surely exists and someone really have seen one :)

I have the original blue Service Manual, and the CD4 is not mentioned or described in there.

I sold mine 10 years ago to a customer in California, and from all the curiosity about it now, it appears that I should have held onto it!

Thanks for checking the manual for us. I don't think the Bg 3400 is extremely rare, but seems like any with the CD4 decoder fitted or the optional CD4 PCB itself is a very-very rare one...
