Original Blaupunkt Radio, 2 DIN's - "Porsche" slide switch...and... Options

[turk22]

All,

I have some pictures of my radio, which certainly appears original to the car, and I have a couple of questions.

First some front shots: (Note the black button on the side on the station select buttons, it pushes in and out, anyone know what it does??) I have not seen any other pictures of a radio with the "Porsche" AM/FM slide select (what have I got here?).




Here's some pics of the tags, what a bitch to get these pictures. In searching this site and google I've found some links to the FTZ-Nr. U108 number, but none look like this radio.




It has two DIN jacks in the back, both have 'tethered' plastic covers. (I'll try and get clearer pics, but the blood was rushing to my head..) One cover has two 'pins' in it, and the other has 4 'pins' in it, the pins appear to be aluminum, but not really sure:



anyone else have a radio like this and can tell me a bit about it?
thx,
Turk

So I actually do have a couple of questions (not just being a post whore..)

I want to put in the correct faceplate with the correct fabric applied. I think in looking at AA that this would be the correct option:

(Unless someone has a faceplate they would like to sell, I'm interested!)
That would be for a 73 dash (2.0 with center console if that matters...)


Another question is the screw type of adjustment in the face of the radio. I'm still looking for the balance adjustment of this radio, and I suspect this may be it...but not sure:


Another question is the fact that I have dual reostat's on both sides, the left(driver) side is the bass/treble adjustment and has the second adjustment knob:

The right(passenger) side has one as well, but I don't have the second knob here, and it appears this is the AM/FM switch, as I see the green FM indicator behind the number 10 on the glass face start to move when I turn this. Its very stiff, and I don't want to force it:


Anyone know where to get the knobs for this radio, especially the 'back' knobs. If you have some to sell, I'm interested!



Appreciate any insight on the questions, or parts needed, thx,
Turk
