Notes

Designed as a "Local Station Receiver". EE: We believe that the British 940A has been originally made with the tube line up of Mullard SP4 and Mullard PM24M and not Philips E446 and E443H but 1821 as rectifier (not G1064) as stated by other source. At least later British versions show 940 A/15 (940A/15) on the plate.

philips: Variance of the model

Hallo everyone,

I've got one Philips 940A radio with some peculiar features. As first, it is in a wooden cabinet, what I have seen only by Czech 944A, but it has different speaker-grille at the front. Mine has the same as UK and Dutch bakelite cabinets. (by mistake, I have uploaded its photo at the Dutch model-page). Also, as far as I know, Czechs have used the Dutch chassis. 

Further, it has UK chassis, but Philips tube-line: E446, E443H and 506.

The most strange is the dial disk! Instead of wavelengths, it has the names of stations - green for MW and red for LW. According to those stations, it was probable made for east- and central European market.

All parts and the wiring are original, except that I had to resuff Philips "padestoel" electrolytes.

Has anyone seen such model, or can locate its manufacturer?

Thanks for help and best regards,

Dejan

Dear Mr. Momirov.

I think your model is identical to the Philips-London 940A, except the case.
See also the imprinted letters MOI ... (See picture).
Please make a model suggestion as a variant (wooden housing).
The tubes are interchangeable.
 
Regards WB

Dear Mr Bauer,

Thanks for your coment!

My radio diferes from UK model not only in casing, but also in the scale-disk. What do you think about this? The names of the stations on it do not seem to be intended for UK market, by my opinion.

Hello Dejan,

there are remarkably many German stations on the dial:

Heilsberg = location of the Königsberg transmitter, (now Oblast Kaliningrad), Breslau (now Wrocław, Poland), Frankfurt, Berlin, Leipzig, München = Munich, Langenberg = location of the Cologne transmitter, Zeesen was the location of the Deutschlandsender, Mühlacker = location of the Stuttgart transmitter.

However, at the time Philips was not at the German market, perhaps in Austria.

Best Regards,
Jacob

As from 1934 Philips had a radio production facility in Germany: "Philips-Rundfunkgerätefabrik Jägerstrasse" in Aachen.

The many German stations on the dial may call for a origin of a German speaking country, but the Philips tube-line E446, E443H and 506 contradicts an origin of Germany, as then it would be fitted with Valvo tubes, the German branch of Philips, as well the dial lamp made by Philips England.

As for German speaking countries then only Austria and Switzerland are left.

As the type plate of the chassis is missing, the origin of this radio may remain unknown.

There was not even a similar Philips radio model on the German market. Philips radios produced in Germany just became really succesful as the A- tube line started (AF3, AK2, etc.), that's why I assumed Philips Germany has started its production not before the A- side-contact tubes. By now, I never encountered radios from Philips Germany with older tubes.

Best Regards,
Jacob

Probably this set was not intended to be exported to Switzerland, as in Switzerland in 1935 the Swiss german language transmitter "Beromünster" was already active and Switzerland never had been allocated a long wave frequency, so a set with longwave coverage would only make sense to tune in stations of the surrounding countries, german and french longwaves were never very popular.

Only my five cents from Switzerland
Martin

Thanks everyone!

Very interesting and useful coments, but I am afraid the origine of this radio may remain unknown. What I can say about that, is: I inherited that radio from my grandma who (we) lived in small town Zrenjanin, northern Serbia. It was purchased just before WWII, probably by local distributer, and maybe in Hungary or Austria.

What surprises me is that no one within RM community, being member or gast, hasn't report such an set. It must have been a small (maybe experimental) series which was ended by onset of the war.  Those are just my speculations, but I am sure I own a very rare set!

Best regards,

Dejan

The set 940A, in bakelite, was produced in Czechoslovakia under the name 944A.

  1 In a 940A/15 these valves are used: SP4-PM24M-1821

  2 Dear Aad
Thank you for your post to the model. This is very interesting because those tubes are not direct substitutes (to my knowledge). Therefore I beg you to introduce a new model (see the link on the HP):
940A/15 (940 A/15)
Into the variant field you put SP4

Please put into the normal model with the E446 also E446 into the field variant - just as a changement on the existing model.

Please check if the rest is the same for the new model - if you can. It is also from GB since the tubes are from Mullard. Funny is only that they did not name the DW2_Mullard  instead of the same 1821.

It would be very nice if somebody could check which continental tubes had the exactly the same electrical data and the same base. then we could give alternatives to those two British valves. Maybe there are also or only similarities - but also then we could name the alternatives which normally function without problems.

  3 Dear Ernst,
                  interesting, but in actual fact these valves
are interchangable; and very close in characteristics!
I've frequently found similar situations with Philips sets;
as you probably know, the suffix "/15" indicates this was
made in Britain, or at least for the British market, and
the Mullard equivalent types might be fitted instead of 
the Philips "E" types; for some reason this didn't apply
to the rectifiers,- and 1821's, 506's etc. were quite
common.
p.s. - since writing this, I have now found documentation
which mostly confirms the above, although the rectifier
isn't specified. see - www.radiotechniek.nl  (search 940A)
I have seldom seen any of the 5 pin Philips "E" series in G.B.
Most seem to have a Mullard direct equivalent, which is, I
suppose, not surprising, as no doubt many came from Holland
anyway!

Best regards,
                      John Turrill.

  4 Thank you , John, for your research.
The result is now worked into the model.
Aad has not to open a new model 940A/15 because we believe now that at least later versions bear the /15 on their plate. In any case often such models are named just by model type and without versions. Therefore I have put into the name both versions to enable users to find it either way.
