Hello everyone,
I'm hoping someone can help me out with a question regarding a vintage amplifier. I'm trying to figure out how to connect an external source to it, but I'm not sure how to do it properly.
The amplifier has two connections, one for a Tape Recorder and one for Turntable, both requiring a 5-pin DIN plug. However, I'm unsure if the Tape Recorder connection is input only, output only, or both. On the panel, I noticed that there are options to select the turntable input and different radio frequencies, but I don't see an option to select the Tape Recorder input.
I have bought a 5-pin DIN connector and plan to experiment with it to see if I can get the amplifier to receive an audio signal through the Tape Recorder connection. If this doesn't work, I'm also considering building an attenuator to feed an attenuated audio signal through the turntable input, following the schematic found on this website: "https://www.epanorama.net/circuits/phono.html". However, I'm not sure if I should follow the design exactly or if I should customize it for this Saba amplifier in particular.
Unfortunately, I haven't been able to find a manual for this amplifier that explains the specifications of these DIN connections. I did find a schematic on this website "http://radio1.3dn.ru/manual/saba-konstanz-18-stereo.pdf", but I don't have much experience with electronics aside from basic soldering and using a multimeter.
I'm simply hoping to be able to connect an analog audio signal to this wonderful vintage amplifier. Any advice or assistance you can provide would be greatly appreciated.
Thank you in advance for your help and suggestions.

I don't know if the 'Stereo' switch is a push button or if it's broken, because it doesn't stay down when I press it.

Thanks!! but the issue is that apparently that source does not exist in the panel... how do I listen to the tape recorder?
The switches are:
The switches are:
- On/Off
- Long Wave
- Medium Wave
- Short Wave
- UK (FM?)
- Phono
- Stereo (push button? what is the purpose of this switch?)
Wow, thank you a lot!
I'm not able to understand the schematics. That means that the Phono switch works for both DIN inputs and neither of them is preamplified?

The Phono input on these old radios is for ceramic cartridges delivering alrady line level signals only - not the more modern magnetic pick ups. Therefore, there is no preamp nor any phono equalizer network!
The Stereo switch seems to be broken as it should stay in the lower position if pressed. It is mainly used to switch on the internal stereo decoder for radio reception.

I made a DIN to miniplug adapter following @wiseoldtech instructions. I couldn't tell if the layouts I found online showed the information on the pins side or the lugs side, so I had to watch this video.
It worked great. But I noticed that the volume of these inputs is something like 6dB lower than the FM radio. Thinking of maybe getting a preamp like this.
The stereo switch that doesn't stay down works for these DIN inputs too. For some reason when playing a 100% panned sound on one speaker, the other speaker isn't completely muted. The adapter is well made, I already checked it with a DMM, so it's not its fault. Anyway, it's good enough.
Best regards to all
