'yellow light' AM/FM radio?
« on: August 06, 2013, 12:56:09 PM »
A few days ago, a friend suggested that there were yellow light am/fm radios, that may have been used part of the year on 1969 Camaros.   All I've ever heard or seen were blue light.   Is there any truth to that??

Yes, toward the end of the year when the 1970 was supposed to debut. But because the 69 model year ran long, the yellow light AM/FM was used. The exact transition date is unknown, but it appears to be sometime in June, 1969.

This is also mentioned in John Hoopers book The 1969 Camaro reference book, along with how many were sold( 8271 yellow, vs 2359 blue). The yellow also had a different option number of RPO U69, and the blue was RPO U79. It might be a handy book to have in your library.
John Hoopers book covers some different aspects than Jerrys, I wouldn't say one is better than the other, most of the info is similar of coarse, but Hoopers book has some neat little tid bits, like the RS option added almost 30lbs to the curb weight of the car along with many other interesting options and facts. You may find it a good read as well.

U69 was the AM/FM Mono radio option.  Both the Blue light and the Yellow light AM/FM Multiplex radios were option U79.  The Bluelight radio had the separate multiplex amplifier unit installed up above the glove box, the yellow light version was a self contained unit that didn't require the separate multiplex amplifier and was the immediate predessor of the 1970 version of the AM/FM stereo radio..

I've had that book since it was first published, and I probably read it cover to cover way back, but obviously didn't pay enough attention to the am/fm radios, since my car only had the am... :)

So the U69 were yellow light only then? thanks for filling in the blanks about the 2 radios. It is interesting that both had 2 different colors yellow and blue versus the rest of the dash lights which use more of a greenish  hue.

Adding to this post. I have a yellow light am/fm 4 speaker stereo with the separate multiplex unit mounted above the glove box. The date code on the transistor is 6916. The car is a 05A Norwood build. I have pictures if needed.

Were the yellow light radios coded the same as the 69's or would they have the 70 part number?

Austin...   Mark's post above seemed pretty authoritative to me, and I'm leaning taht way (although I know little/nada about the AM/FM radios)...  What you stated was inconsistent with what Mark posted...??

DAVE BEEM's Survivor L78 Conv 05A has a Yellow Light AM/FM external Multiplex and tons of docs.

The Multiplexer is installed using well nuts into the wiper well. So if you run across a car with holes on the pass side into the wiper cowl it was a AM/FM multiplex car.

This is the AM/FM Yellow Light multiplex mount in Dave Beem's  05A NOR survivor L78 convert.



This shows the kick panel speakers...




Here is the window sticker we got from the original owner.

OK, Ya'll are confusing the hell out of me!  In the past, I have understood that there were only two radio's before JUNE!  The U63 AM radio and the U79 blue light with external amp mounted above glove box, accessed through wiper area on cowl.  This theory just flew out the window, along with the internal amp yellow light being the third radio available after June!

Mark, You mention a U69 mono AM/FM radio.  What was this radio?  What time frame was it used, (build dates)?  WAS the U69 mono option available at the same time the blue light U79 was available??  Would the U80 option be needed for U69?

Danzo, YES, please post some photo's of your yellow light system.  James, do you have any more photo's?

Ok, now we have at least TWO examples of Yellow light's with external amps in MAY!  What gives?

1) Does the AM/FM mono *U69* radio have an indicator lamp??  if so, what color?   I'm suspecting no lamp...
2) Does the blue/yellow lights on the stereo radios indicate 'stereo' reception, or is it a 'signal strength' indicator?
3) How many speakers did the AM/FM mono (U69) radio come standard with, and where located?
4)  Was the rear speaker optional for all the radios, or just the monaural radios (ie. U63 and U69)??

It would be good to see some photographs of the various AM/FM radios, as I suspect most of us have only the standard AM radio (U63 with one speaker in the dash) as I do...
