Anybody recognise this "Noval" car boot find?

[Wishiknewmore]

Hello,
Does anybody recognise this French radio, the only thing that I can see on it is "model NOVAL"
The valve line up is ECH81,EF41,EBC41,EC41,GZ41 and magic eye indicator EM34
I was told "it works!" ...but I have made no attempts yet.
Any ideas as to where to find a circuit diagram would be wonderful!
Many thanks in advance
Philip

You could try one of the French forums listed in this thread:-

What a tremendous find!

The output valve will be an EL41, not an EC41.

That symbol on the grill look like the one used by Radiobois; Paris

I don't think they have this exact model in the Radiomuseum though

I wonder if who ever it was made this one too:

'50s French radios of this ilk were pretty much generic. Find one with the same valve lineup and chances are the circuit will be near enough.


It's got a bog standard Mullard/Philips valve lineup anyway; unless the designer was on trop de vin it'll likely be derived straight from the applications data of the day.

Nice find by the way- I've got a soft spot for the more outrageous French sets of the period.

Mention of glass tube caps reminds me of a Schneider set I have. I suppose other makers in France used them too, but the pierced part back, holes rather than slots, is also very Schneider ish. That's a new word for google.
The back on my set has a model name only too.

That's interesting, until now I hadn't realized that there was such a thing as a GZ41.

The badge thing on the grille looks the same as the one shown on this page (scroll down to post 2821):

I don't think British manufacturers used it at all, but it was quite popular in France, as was the AZ41.

I wonder if it originated from Oceanic?

Wow - nice ...... and not as outrageously 'Baroque' as some French offerings !!

[ms660]

There's also a Spring 53 with the same badge on the grill cloth as in post#9...So near yet so far.....

Thank you for responses so far, certainly making progress
The EC41 was a typo by me
Is it possible that the ECH81 is not the original and is replacing a ECH41 or 42 (or is that not how it works?)as I don't seem to see any totally matching line ups?
Many thanks
Philip

It's quite possible a small French maker used whatever was easiest to hand. One of my sets has a real mix of B7G, B9A and octal eye valves in it.

Also look out for capacitors valued in cms. 1cm is about 1.11pF. It's the old cgs unit for capacitance. Unless it's tuning something, 1cm = 1pF is close enough.......

I reckon Lawrence's find is close enough! There's several other "modeles a identifier" with very similar layouts and lineups so the chassis probably is a generic one shoved into the local shop's choice of cabinet.

The IFTs look very off the shelf Phillips too.

I suspect some people like me are thinking , How much was it you lucky well done in finding it , Mick.

[Andrewausfa]

Yes I'm another It's in pretty good cosmetic condition too. Excellent find.

It's not inconceivable, as the 8-pin ECH41/42 are electrically similar to the 9-pin ECH81 (the recommended replacement, when the 40-series valves became obsolete); but Continental manufacturers seemed less averse to mixing valve bases within a set than British manufacturers. So the set could easily have always had those valves from new. Are there any signs that its holder has been replaced?

French manufacturers seemed not to trust the heater-cathode insulation of the EZ80 / 81 at first (even although it was under less voltage stress than that of a UY41 / 85 would be), and persisted longer with separate rectifier heater supplies while others used single supplies.
