GE model numbers from the '60's started with a "P" prefix for portable radios, a "C" prefix for clock radios, and a "T" prefix for table radios. I think this model number system may have continued into the '70's; but, how far into the '70's was this model system used before they switched to the 7-xxxx model number system?

Also, later GE radios had a strange four digit date code. Does anyone know how to read these date codes?

Post several examples of what the date codes look like.

GE dates codes from the 1970s - 90s have been discused this site and others, but it's frustrating that they seem to be impossible to locate now ? The question has been asked several times on antiqueradios.com in the past with no answers. !

I myself have several SuperRadio's along with other GE's I'd like to pin the exact date on from the four diget code.

Will a GE expert please step forward ~

The down and dirty is the 2nd digit in the "mystery code" is the last digit of the year.

This date backs to at least the early 1960s. I believe this number includes a plant code, shift code, etc. among other things.

As stated before, GE originally used just a numeric model number. Soon the writing was on the wall as they were so prolific with manufacturing consumer electronics, they needed a way to keep the numbers at bay.

Around the 1957 model year, GE went away from "XXX" model numbers and went with the model prefix. C-XXX indicates clock radio, T-XXX indicates table radio, P-XXX indicates portable radio, etc.

After the three digit specific model was a letter suffix on most. "A" signified the first design run. Every time a change took place (whether it would be major, like a cabinet redesign, or minor like a volume control pot part #,), the letter suffix changed to the next letter. For example the low-cost C-403A clock radio was the first design run, its basic design spanned nearly a decade with chassis redesigns, cabinet redesigns, with the last model being C-430H.

Now back to the original question. Even going back to some early 1960s GE radios, you can find an ink stamped 4 digit code on the tube label. Again the 2nd digit represents the year of build. I did find on at least one late 60's clock radio, the code appeared to be actual date code with the first two digits signifying the actual year (67=1967) and the second two signifying the week of the year (just like a capacitor date code). However, this seems to be the exception to the rule. Now let's say the 2nd digit of the "mystery code" is a 2, this can be tricky...1962? 1972? 1982? This is where you have to get educated and look at what you are looking at. Is this a walnut grained styrene radio--probably not 1962! Digital tuning radio--probably not 1972!

Around the early 1970s GE started using the 7-XXXX model arrangement. The 7 signifying consumer electronics radio equipment (or something to that effect). I've seen some early examples of this where on GE boxes shows BOTH style of model numbers as to ease into the transtion. So in other words you'd see 7-XXXXA and then printed below would be (C-XXXX).

Hope that helps!

I hate to be one of those guys (I am new to clocks) but I still do not get it. I have a General Electric PROGRAMMABLE Clock Radio. The Date Code is 5109. The Serial Number is 072351. The Model Number is 7-4870A. From the earlier post I believe the "A" means this is a first generation clock for this model? I came across this by accident but am new interested in similar MCM clocks...any help would be appreciated...ESPECIALLY if you have a Panasonic RC-6030 you do not want anymore :-)

Probably a 1981 model, given the second digit of the date code is 1. It could actually be a '71, '81, or '91 model; but, the description sounds like something from '81.

I'd agree seeing how it is in Sam's Photofact #2027 from 1981.

Hello, I am new to all this. I would like to find out how old my clock radios are. They are (two of them) a GE Clock Radio Dual Alarm Model 7-4621A . They were baught at the same time and have two total different date codes. first one: 2324 , the second one: 4509P. I do believe they were purchased at wal-mart in the early 90s

I just wanted to add, I am pretty certain the last two numbers are the week of the year. I've never seen them have more than a 52 or 53 which is a pretty good indication. They used those codes all the way into the late 2000s when Thomson stopped selling under the GE and RCA brands. Actually RCA telephones still use that 4 digit code today.

GE four digit code started with 1959 and went into '69 or so. Prior to '59 used a three digit code of year & week.

Decodes as day of week, year, week.

1933 decodes as Monday, 1959, week 33.
2135 Tuesday, 1961 week 35.
3222 Wednesday, 1962, week 22.
5003 Friday, 1960, week three.

Occasionally you'll find a Saturday built unit that first digit is six. Usually those built in Oct/Nov with anticipation of holiday sales.

Warwick used similar system for Sears Silvertone but year is first, week is middle two digits and day last.

Pict, P806A built Thur, 1959, week 10

Thanks for the info on the day of the week number! Didn't know they used it that early either. The code did continue through the 70s-80s and the Thomson buyout though, when GE branded radios ended in late 2007 they were still using it, even into 2008 on some RCA branded Super Radio IIIs.

You have to be careful of speculation.

Unless you have official GE documents to go off of.

I stand by my “2nd digit calendar year” indicator.

However, there always seems to be unexplained exceptions to the rule—in regards to the day/week indicators you guys are talking about.

So how does a tuning capacitor have a 40th week of 1965 date code, while the supposed week on the model tag indicates the 20th week of 1965 ??? :)

If date is in question, one refers other components for their date. If all original are in a similar range, stamp on model tag is incorrect. Forrest Gump said it best about things happening. I have no doubt the four digit code of day, year & week is correct system. I can't change fact a few were stamped incorrectly or missed their stamp.

Pictured is a P-807G, built Tuesday, 1963, week 07. Tuner built 1962, week 42. In transistor radios, electrolytic caps, tuner, speaker, xfomers etc. will have similar dates. Not to say once in awhile there are parts dated far prior of others. I have a P-780H components are all in 6540 range, excepting tuner has 6502 date. Just have to assume stocks were not always rotated. Most components were supplied by other mfgrs, I've found three different speaker mfgr for P-780 series, none were GE.

BTW, note GE's warranty.

Warwick used similar four digit code system for Silvertone but decodes as year, week(two middle digits), day. Their system started back in '50s, dunno when it ended.
