Default Model identification - Help (Mediator?)

Hello all,
I am trying to identify this model set (images attached).
The valves used are AZ1, EL41, EBC41, EAF42, ECH42. I believe it is branded Mediator.
I was able to find Philips models with same chassis (for instance BX416A, and BV429A). Nonetheless, this set has an (unusual to me) back cover socket and selector. The selector turn on the radio and has 2 options (or AC voltage or 6V voltage that I assume would be for a battery pack).

Has anyone came across a similar model or a philips equivalent one?
(images attached).

Thanks in advance,

Diniz from Portugal

Everything about that set shrieks Philips made. Same black tar capacitors, same controls (pots), same mains transformer and Philips-style coils. It even has a Philips-style model label. I'll have a hunt around and see if I can find anything.

Looks definitely like a Philips set by those black tar covered caps and those IF cans

That chassis label suggests it's a Mediator M379Z which certainly conforms to the style of model number in the Radiomusem list. Unfortunately it's not one that's there.


Mediator is definitely a Philips brand- looking at other Mediator sets in nvhr.nl throws up service data with Philips plastered all over the front page!

I wonder if it's designed to run on the 6 volts from this PSU (Click on AU1004 then do the Captcha):

Like this Philips receiver can:

Smile Re: Model identification - Help (Mediator?)

The cabinet put me in mind of the Philips 341A.

But following Lawrence's lead to the doctsf site, I noticed that you can search by valve line-up. Halfway down there's a NSF H304A which looks like Diniz's set

Reading that history of NSF further, though, reveals that they used the brand name 'Aristona' to distinguish themselves from a German brand also called NSF (Nürnberger Schrauben Fabrik), and there's radiomuseum entry for the Aristona H304A!

Translation from the Mediator manufacturer page on Radio Museum

Mediator (Philips brand in La Chaux-de-Fonds): From the start of production in Switzerland, Philips also manufactures the Médiator brand. Sale by Medialux AG, Zurich. End of radio production for CH 1955, for TV end of January 1973. Company history [1-164] Mediator will remain an import brand for many years. Incidentally, from 1950 onwards, the brand was written on the e.

There are some Médiator models that were made for the French market (possibly made there). Service documents for these models were initially issued by the French CCR, and later by Radiola and Philips (F).

Thank you all for the information provided. It has been helpful to find the similarities between models.
I've been following the Philips BE 321 Z schema, but already found some wiring differences... I pretty much believe is was already been in the hands of someone else
Let´s hope for the best...

@Lawrence: I believe the AU1004 matches the socket I have here

I thank once more everyone of you that spent some time looking at my thread.

Regards,
Diniz from Portugal
