Someone gave me this radio but I know very little about it. I like the fact that it's stereo, if it still works...

Unfortunately, there is no faceplate.

I was thinking of installing this in my 73DD. Would certainly be closer period correct than the current early 2000 unit.

Let me know your thoughts

Well it's a Blaupunkt.

Look for s/n, model number & mfgr. date stampings on the metal case sides, bottom, top, back; & inside the case if you can get some access there may be a paper label with it. Then you can do a google search, or contact one of the retro radio restoration places for more info.

Good Luck with the mystery!
Tom

It's not a Sapphire!

Well, it looks like it could be a 72 or a 74 Frankfurt depending on the missing faceplate trim, if I look at Jeff Bowlby's 914 reference.

Now lets test it and find the missing faceplate.

It is a US market Frankfurt stereo.
It's the most 'correct' looking for our early dashboards.
The chrome bezel is the perfect match to the bezel on our heat/defrost controls.
The right dash plate is fairly easy to find.
Also, all 914s have two built-in speaker enclosures, so no 'modification' of door panels is necessary.
Rich, full Stereophonic sound !
CW approved.
Now find a correct antenna.

Good find. There used to be a paper sticker on the side with the model information. You can also use the rear DIN plugs to hook up an iPod (or other music source) to the radio, so it can be updated. A manual (or automatic) Hirschman antenna should complete your project.

And yes, please don’t cut up your door cards for speakers. The kick panel ones can work well enough.

That looks like a correct late '73 or '74 Frankfurt US model....the date code should be 'E' or 'F' on the side of the radio.

Once you have tested it and it works, I can point you in the right direction for the needed parts for installation. The correct chrome trim piece with the recessed center bar is expensive same with the correct side clips.

Had a Frankfurt in my 73 Capri V6. Great little radio. It was also a fantastic car back in the day.

Unfortunately, no stickers.
DIN plug? Under one of these 2 caps? You mean this radio has actually a low signal input? Wow! Any modification needed for this?

Thank you for the input

The plastic covers on the back hide some DIN plugs. They allow you to divert the signal from the tuner to the amplifier section of the radio. Here’s a schematic I found to add an iPod input for my Frankfort radio. This was for a mono radio, but there is one also published for the stereo version. Perhaps Mike Fitton has a copy.

I found the step schematic as well.

I have this same radio in my '74. It's very versatile. Input and output adapters for the din sockets on the rear allow the use of an external amp and iPhone/iPod inputs.
Mine connects to a 4 channel amp in the console connected to a sub in the passenger footwell and side speakers mounted in enclosures purchased from 914 Rubber.
You can easily find the adapters on eBay.
Good lock with it.

And here they are!!! I'm amazed at this old radio.





And to think that this was design and built almost 50 years ago! To think of external source and amplifier, they were well before their time. This is getting really interesting!

This visual should help with the installation.

Nice exploded view, thanks Mike

This will not go into a concours car so I'm sure I can easily fab a rear support (#7). As for 8a and 8, I'm sure I can design something and print parts that would do the same job.

The 914 version of #11 is available from 914 Rubber (I think).

As you mentioned in a previous post, #12 is probably the most difficult one to find. I did see some in Germany but the center bar is not recessed. I could definitely tolerate that variation.

Here is a picture from Vintageblau, anyone dealt with them?
