Replacing 5-pin DIN inputs on a Telefunken Radio? +weird speaker output?

hageir · 16th January 2008, 09:03 PM

Hi!

My name is Geir Helgi and I live in the good city, Reykjavík, Iceland

I went to an antique dealer today and found a great old Telefunken (5x)Tube Radio for $50..
I bought it because it's got inputs for a phonogram and those old portable reel to reel's (A.K.A. Magnetophones?)..
(The inputs are like a MIDI input or DIN, so it's 5 tilted pins in a half-ring and one hole in the middle..)
And it also has a seperate speaker output, with the weirdest plug I've ever seen (one boxed hole in the middle and a smaller "flattened-oval" beneath)

I want to feed something trough the radio and back out, into something else, so the audio travels through the tubes..

So my question is can I get some adapters (that would be the easiest way) or can I swap them out for RCA inputs, 1/4" Jacks, etc.?
If I can, how do I wire them?
I need one of the inputs (either Phono or Magneto) and that speaker output..
It also has ceramic inputs for the antenna and something else (ground?)

Anyways, here are some pics I found on the net:

and here's a picture that I've marked:
1: Phonogram
2: Port. Reel To Reel / Magnetophone
3: External Speaker Output

thanks a ton in advance!

Should be able to get 5pin DIN connectors anywhere...

The output connector is DIN too. I usually see them on german car stereos...

OH MY GOD!

That's the one, pheeew, I thought it was some special, ancient WWII Telefunken plug

thanks a million tons man!
I'll head over to some electronics shops and see if I can find those plugs.

Lifesaver!
here's a some money for you

hageir · 17th January 2008, 02:56 PM

ps.
if I can't find that speaker plug, or if it's not powerful enough.
Can I change the cables that go directly into the speakers of the radio into RCA/jacks?
Like those circuit benders do to old toy keyboards to get outputs?

Keep in mind that the DIN speaker socket disconnects the internal speaker if a matching connector is plugged in.

This is a fairly ordinary DIN loudspeaker socket. If you can't find one of these plugs anywhere I might undig one up in the attic.

hey,
thanks for the replies, I appreciate it!

I went to a parts store and bought one of these:

I didn't know that the Magnetophone/Reel input was in+out!

that's awesome!

I bought a 2pin DIN speaker cable "head" so I can wire it to a bigger system/speakers

anyways, thanks a ton you guys, you helped a lot!
especially you charles, offering a DIN plug

thanks!

ok, a small update

I tried to connect my computer to the radio via the rca->din adapter and I got sound!
but it's very, very, very low.. "turntable-without-a-mixer-low"

hehe

so I have to amplify the signal before it goes in?
how do I re-amp line level to "magnetophon"level?

also, I tried the output of the vivanco through the magnetophon output and didn't get anything, can it be that the telefunken is mono (i.e. only in?)

another question:
I'm thinking this nice telefunken is too nice to "mod"
so I'm gonna head to the fleamarket and goodwill to see if I can find a "crappier" one

here's what I'm thinking:
source/cd-player/ipod/instrument/what ever -> tube radio -> mixer/amplifier = digital stuff gone through analog tubes and stuff (i.e. the horrible word "warmed" up

)..

is this possible?
would I have to seriously mod the board inside the radio to achieve this?

Dear Helgi

Your Telefunken is Mono although it has the 5-pin Din connectors.
Nevertheless it should play very well on a pc-soundcard if you press the "TA" bottom.
I think you just hit the wrong pin with the adapter wire.

TheTellis output-signal on the 5-pin Din-outlet is very low,
connect it to the Microfon-Input of your soundcard.

Have Fun !
