Frede, I must have one lying around. How can I recognize the decoder option from the outside?

Leslie,

You can't see from the outside if a Beogram 3400 have a decoder build in.

You have to open the Beogram 3400. If you do so, you will find the decoder as a big PCB and also you will see an extra small mains transformer.

I hope you have on 🙂

You can tell it the CD4 decoder is fitted to a 3400 as the small black plastic plug on the top plate is replaced by a red LED.

Interested to know if it is a similar module to that found in a gram 6000?

Frede, be patient, the weather is terrible over here, rainy and cold. Have to go to my other "closet" which is about 10km from where I live. Hope to do it this week!

Having had both, it is a totally different shape so they are not interchangeable.

Leslie, no problem - we have the same kind of rainy wether here. I am in no hurry - I just hope you "find something" when you have the time.

Sorry Frede, found one with but unfortanetely no decoder😳. I wonder why you read  4ch on top of the alum. plate and there is no board in it! I suppose you can't use the record player? It's in a good condition and you can have it for free if you want it!

I have had a Beogram 4002 type 5523 with the "4ch"-display between the speed selectors on the top plate 🙂
