'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...

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...

You're correct if by "indicator lamp" you mean the "Stereo" light.

One speaker under the dash

RPO U80 was available with RPO U63 (AM Radio) and U69 (AM/FM Radio), but NOT available with RPO U57 (Stereo 8 track tape) or U79 (AM/FM Stereo)

U79 am/fm stereo had a blue indicator with an external multiplexer mounted in the wiper well as James photo shows. Later in production the yellow indicator (still U79) was introduced. I have never seen a yellow light installed in a 69, but there is enough evidence that they were installed. The rub is that I always thought the yellow indicator radios had an integrated multiplexer (that was the difference and change)and no longer needed the external multiplexer.

U69 mono am/fm was available throughout the year, and doesn't have a blue or yellow stereo indicator.

Question for James, is the multiplexer still hooked up, or was the radio possibly replaced at a later date with the yellow lite and multiplexer bypassed.

Ed,

Thanks for your answers which cleared up some questions I had (and possibly for others)!  :)

Steve, I had that same question when I read James' post... If the 'yellow light' unit didn't eliminate the 2nd electronics unit, it made me wonder WHY they did a mid-year change???  but after 47 yrs, *many parts* have moved from one car to another.. :)

I agree. The yellow light stereo was a self contained system. No separate multiplex unit like the old(er) blue light.

Dave's car was built in very early May, 1969 (05A), so it "should" (I say "should" because that's in a gray area) have come with the Blue light stereo and the separate multiplex unit. If it now has a yellow light stereo AND the multiplex, then the stereo's been replaced and the multiplex isn't hooked up. It can't be! There's no place to hook a separate multiplex adapter to a yellow light stereo.

James, are you positive he has a YELLOW light radio in the car???

Is there another possibility??   ie. that the lamp/lens in a blue light unit was replaced with the lamp/lens from a yellow light unit???

My understanding was that the yellow light stereo introduction was very late, Sept of 69.

Most of the questions are answered in the option sheet: http://www.camaros.org/options.shtml#RPOSpreadsheet
1. no
3. front
4. mono. Kinda hard to add 3 speakers in the back with the stereos.

Ed, respectfully I disagree. I have a yellow light stereo with the separate multiplex unit. This setup definitely came in this car( 1 owner 1969-2013). As I stated in a previous post, the transistor on the back of the radio is dated 6916. The back of this radio has the round receiver for the multiplex unit and the multiplex unit was plugged in! Let me know what pics you would like to see. Never say never.

Kurt brought up a remembrance in the deep, dark recesses of his mind, and after he said it, it kind of jogged my memory too (although I'm FAR from an authority on 1969 radios), that there were actually 3 AM/FM stereo radios used in 1969.

1. The early to mid Blue light (with the separate Multiplex adapter)
2. The mid Yellow light (again, with the separate Multiplex adapter)
3. The late Yellow light (self contained, and actually designed for the 1970 model year)

Mark has yet to reply, but I also seem to remember something about the heat fins on the self contained (1970) yellow light rubbing against the dash??? (Old age is a BITCH!)

And of course I would never speak for Kurt, but this would explain the yellow light radios we're seeing with the separate multiplex adapter.

Been trying to dig thru old posts, my Delco service manuals and some Sams Radio manuals to find out what the story is or was.  Came up with the following summary of 69 radio part numbers.

AM radio is 91APB1
 AM/FM is 91BPB1 (P/N 7307321)
 AM/FM Stereo is 91BFM1 (P/N 7307331)
 AM/FM Yellow light is 91BFM2

 Numbers decode as:

 9=model year (1969)
 1= GM Division, Chevrolet, 2= Pontiac
 A= A-Body Chassis, B= B body Chassis
 PB= Pushbutton, F= AM/FM
 B= Pushbutton (FM only), M= Multiplex
 last number = release number

 The multiplex unit is 91FMP11
 The under dash multiplex is 91BMP21 (dealer installed only)
 The under dash 8 track is 91BT411
 The under dash multiplexed 8 track is 91BT421
 The console mounted 8 track is 91FT221

The 91BFM2 shows up in the March Sams Radio Repair manuals around March or April of 69 and it does have an external multiplex unit attached to it.  The only differences I can see between the FM1 and FM2 is the transistors change to DS-74s from DS-27s,the dial lens and the stereo indicator lens part numbers change (they are the same part numbers used in Cadillac multiplex units at tis point).  The part number on the lenses change and while the parts list don't identify color I'm ASSUMING the indicator lens changed from blue to yellow at this point.  As a running change with no other apparent installation differences I would guess that it would be possible that a late March car could get one, while later cars could still get a 91BFM1 radio unit the original units were used up.  As a low production option, I don't know if the assembly plant would have a stockpile of them, or if they were delivered to the plants in small batches over time.  I can not find another radio part number for the multiplexed stereo that was specifically identified for the 69 Camaros later in production that did not have the external multiplexor.  If there is a non separate multiplex unit radio used, it must carry the 1970 model year tags.

thank you very much Mark!   Between this great information that you dug out, and the info provided by others in this thread, we can probably put together a pretty complete story re the 1969 radios available throughout the year... :)

The only things we didn't address in this thread were the antennas...  I *think* the radios with FM capability required a different antenna than the base AM radio??

Gary the FM equipped cars had a fixed length mast and AM equipped cars had a adjustable length mast. The rear antenna option was not available on FM equipped cars and D80 (spoiler equipped cars).

For those who want sound and look, the 70 Monte Carlo and Chevelle fit and look like the 69 yellow light.

Thank you Mark. That does support what Kurt and I seemed to remember.

I believe we've also discussed the 1970 AM/FM being installed in the very late 1969 Camaro because of the extended production, but it appears there's no conclusive data (proof) regarding this?

Just for the record, none of my manuals that I have are for late 69, so there could be another part number out there that got added to a September parts manual, or radio service manual for an AM/FM stereo radio that had an internal multiplexor. So there may still be one out there, I just can't find it. 

My Delco manual is from early 69 and my Sam's radio manuals are issued monthly and I have them for most of the 67 to early 70 production periods, but they don't tell me specifically vehicle each radio would go in.  Sams manuals are kind of a pictorial guide to components on various different radios used in all Car lines in the late 60's and early 70's.  They were probably used by radio repair shops to repair broken radios back before we just threw a piece of broken electronics in the trash. They have pictures of the individual board inside the radios and identify the part numbers or model of the components on the board, much like the Delco manual do, but they cover a ton of different models, and probably not all of ones that interest us.

I have a few radio service manuals and will see if they differentiate the blue light and mid-year yellow light.
Thanks Ed & Mark...

Thanks for posting Ed and Mark!

It would be interesting to see the tag of a yellow light integrated (late) radio.

I agree..  but I'm suspecting they are 'notated' as for '70 models...

Those of us with 'late '69's are lucky this way, having many parts that were ordered for the '70 models, but used on the late '69 cars (or early '70's if you will!).. :)   This late yellow light stereo radio is just one more example to add to the list along with the 'dripper valve covers', 'C' stamped differentials, etc...  Who can add to this list?  :)

How about the drivers door blue VIN decal, and change to door, with two locating peaks for sticker location.

I seem to remember an hi-fi article I ran across a few years back that noted the differences in automotive radios and in particular GM being at the cutting edge at the time that affordable FM sets came into our cars. The Blue light and Yellow light models had a different crystal tuning set which apparently had something to do with weaker FM stations being locked into frequency receivership better with the new design. I've never opened one up so can't say this is true for sure or why the indicator light would have changed since the unit sticker would have clued any repair person into which unit it was.
