Braun CD4 demod

[winopener]

Do wonder what kind of schematic there is inside... Braun was well known for their razors, so... they must had borrowed some other ideas for that:

Braun made a CD-4 demodulator? That is a kick !

Braun electronics were excellent. I loved their speakers as well. My main quadraphonic/6.1 surround system uses all Canton speakers, very similar to the ADS/Braun designs. Every time I get the urge to upgrade, I just listen for a few minutes and I remember how good these German speakers sound. If I was in the EU, I might think about that demod. Just because they make razors ... remember that Yamaha makes motorcycles and pianos.

The Braun CD-4 demodulator was actually a JVC 4DD-5 just like the Marantz CD400. All Braun did was wrap a new case around the JVC board. See here

Nice detective work !

but you have to send it in to sharpen it after a while.

Can't say i'm suprised... that board looked familiar.

It's curious where they choose to put those RCA jacks

Yep, I can verify that. Pulled the case off my 4DD5 and held it up next to the monitor. The Braun is not German, it's Japanese! It's a 4DD5 rewrap. The Braun case appears to be all metal, so it should be shielded better. It's a decent demodulator.

This might require a 240 V AC supply.

This might require a 240 V AC supply.

It says right in the listing "Rare Braun CD 4 DeModulator. Made in Germany. 120/220volts."

Cool/Interesting that the labeling is all in German. Foreign built equipment seems to always be labeled in English which must piss off speakers of other languages!

Sorry, but Braun is a relativ small but old (good) german Companie, usually not exporting to US.
There is not so much to translate except: Eingang = In, Ausgang = Out, vorn = Front, hinten = Rear, and the rest is well known by everyone who is involved with that.
(As for me, I have more problems to translate every government formular into spanish, 'cause here is nearly nobody speaking english, a big difference to germany ..)
220V is old, now it's 230V. Best you take a look inside for the real used Voltage and use a cheap external supply. But it was already running in US...

(think how many chinese are there ...)

 

[MidiMagic]

Odd. I searched the entire listing and didn't find that.

I searched again. That text is in a store listing.

120/220 volts makes no sense. The high voltage must be exactly twice the low voltage.

Here it's 120 V and 240 V.

Cost was the main reason Europe went with 220 volts (now 230). Counterintuitively, higher voltages allow the use of thinner wire, meaning less copper in the early days of power lines. Power companies could save money on wire by using 220 volts rather than 110. Berlin is one example.Jan 13, 2020

Actually, Braun is a wholly owned subsidiary of Procter & Gamble (a US company) since 2005... Back in the seventies, a friend of mine had one of their record players. It looked well cool!

In the 2011 anime series Steins; Gate the hero/protagonist lives above a TV repair shop. The owners name is something or other Japanese, but generally referred to as Mr. Braun, a direct tribute to the electronics company.

And yes, that stands for Cathode Ray Tube...
