UNABLE TO IDENTIFY RCA SUPERHETERODYNE RADIO
5/20/2007 9:09:34 PMVal
I have recently come into possession of my grandfather's old RCA radio, and have been trying to research it's background, but have been unable to locate any information about it.
There is a label on the bottom of the radio that says: Model 5QR 75X Superheterodyne, Made in Western Germany for Radio Fernseh Electro 6.m.b.H.
An associated company of Radio Corporation of America.
It has push buttons for different ranges, with four scales identifying the countries reached by each range.
There is also a dial that says "Ferrite Antenna".
I know that it was purchased sometime in the early thirties, but that is all. It is in prime condition, and still looks new.
If anyone can help me find information about this radio it would be very much appreciated.

Hi,

First of all, if it says "West Germany" it is well to note West Germany did not exist as a nation until at least the middle of 1945 and I believe some items from that year few years may even have said made in occupied Germany for a time period. So it is well to conclude your radio was made after 1945.

Another thing to do to help others help you in identifying this radio is to look at the tube compliment and list them here with the question. Also I am not sure of the year of introduction but ferrite antennas were a little later than 1930's. But I am sure it is a nice radio no matter what year as the European models seem to hold up well. So maybe the problem can be solved with a little more information.

Thank you Edward. I will look at the tubes and get more information on them. The reason I assumed early thirties was from my Grandmother telling me years ago that it was the first item they bought after they got married in 1932. I guess either her memory was a little mixed up, or they didn't buy anything for a very long time!! I will get back to you.

You might check "under its hood" and check for its tube complement and see if it is using the old school tube complement of foreign derived ECC / ECH / EL series of tubes or the later 6AK5/6BE6/6BA6/6AV6/6X4 Amerikanski line up. And, if of the later lineup and supplied with RCA tubes with their 274 EIA identifier, also check for code dates on the tubes to zero on the year that they were installed.

This probably is a pic like it:

Check with :

and see if he still has his unit plus any further info on it.

THAT PHOTO IS IT!!!! I was beginning to lose hope in ever finding it. I have been looking at radio sites and photos for days with no luck at all.
Is that all there was with it was the photo? What site is it on?
I have not looked "under the hood" yet, but there is a label on the bottom that says "Only Genuine RCA Radio Tubes" and then a schematic drawing of circles, squares and lines, that includes the numbers you have given: 6BA6/6BE6/6X4/6BA6/6AV6. But it also includes two sets of numbers you haven't listed: EM34, and 6AQ5. I will get inside and get a look at the actual tubes, and also send a note to Paul Reilly.

Thank you so much for all of this help. As you can probably tell, I haven't a clue what's what, but would really like to know more for the sake of my family's history. I will let you know the outcome if I discover anything more.
Once again, thank you.

Edd - I tried that e-mail address for Paul Reilly but it came back as undeliverable. Do you know how else I might reach him? Thanks.

OOPsies....looks like I typed in 6AK5 in vice the 6AQ5 tube, which serves as the sets audio output tube. Plus, what with the EM34 number, that you supplied, thats the green tuning eye tube that the set uses. But there must be some variance in that, as the photo supplied
shows a rounded 6E5 type of tuning eye mounted in the unit. I remember the EM 34 as being a rectangular laid out display with the
wide green slot closing for its display action. But that is good, as those typically have a longer lifespan, as compared to the older round styles.
No more data available, with the exception of your checking the original tubes for code dates to further zero in on its vintage.

Sorry, I just have this:
http://oscarmoutinho.no-ip.com/MySite/listfiles.aspx?txtDir=@Radio%20antigo

It Works fine.

And I'm looking for the production year.

RCA sold a couple of models imported from W. Germany in the mid-1950's. I believe the model number beginning with "5" indicates this set is a 1955 model.
