Testing a radio at home

[Veronica87911]

We have a 1968 Blaupunkt Frankfurt radio that came with our 912 project, and I wanted to test it to see if it turns on. What is the procedure for that? What do I need?

... I strongly recommend you ensure a speaker is connected to unit before switching on -- powering up without speaker can blow otherwise good radio from that era !

This is the radio...
The yellow wire is the power? The one with the grey lead just to the left next to it is what?
And the one with three inputs on the left?

[Jim Breazeale]

The yellow wire is power, the grey lead on the left is the speaker lead. It is set up for using a single speaker or dual speakers with a common ground. The other grey lead is for the antenna. If you didn't know that you have no business messing with the radio. Your radio is switchable from 6 to 12V and positive ground to negative ground. Make darn sure that it is set for 12V negative ground. Stuff the speaker wires in one of the 2 holes that are close together and the other lead in the long part of the triangle. You will need an old antenna, too.
Good luck, Serge and I'll see you soon.

Regards

Jim

Does this set of images rom Y series technical service book help identification?

This is a European spec Frankfurt from roughly that era but has some similarities





Although not difficult if you are unsure recommend you should get help from someone who is properly qualified on radios and autoelectrics to avoid blowing a neat unit or other misshsp !

Thanks, everyone for the help.
We'll probably sell it (had it at Hershey) or trade it for a Bremen, which is what the 912 came with

If it helps a Bremen V series ......unrestored untested gathering dust ....sitting among probably 25 assorted period radios in storage



Have hundreds of assorted knobs and various chrome plates etc

Also got the V series shortwave Blaupunkt add on unit with black to match pushbuttons I think.
