motorola flyback question
 

hello all, i have a new old stock motorola flyback and have no idea what it came from, 70 degree or 92 degree square tube or round. is there anyone that may be able to figure out what it may have come from i have the number ill list in case anyone has a book or literature on it. 2467564ao7-185.

I'm afraid all I can tell you is that it cross references to Thordarson FLY-399.

well thats a start, thanks. would you have a cross for this one 24d67923a01.

There's a blank next to it in my Thordarson xref guide :(

oh boy i guess moyers was right in saying that this fly was not made by anyone and that it was motorola only, i wonder why. this set i think is going to need one and im just out of luck unless i come across one on ebay.thanks again

Ya never know some flys are electrically compatible, but not mechanically compatible(thus not listed as direct subs). If you can get a schematic for a set that uses the fly you have, and all the wireing and component values are the same as in your set it may work with some creative mounting.

Hate to be the one to say this, but if Moyers said it was NLA it probably is. They would've been glad to sell you one if there was a well-known substitute fly. Just my opinion and based on previous searches.

well thats the first step now that its listed as a fly 399 now i have to find out what chassis it was used in and then compare diagrams on sams for both.

well dead end again since moyers tells me he has no way to back cross to which chassis it was used in but did tell me this fly and 2 other numbers use the same fly,A06,A07,BO6, the same main number but the end was different but the same fly 399.

Well if you can find a library with Sam's folders on file you could flip through the color schematics and pull any color motorola folders from within a few months to years of your set and look for the ID number of your spare fly in the parts lists. I have a couple of boxes of semi-random Sam's folders that I search before I go to the library for one.
I'd search my stash for you, but I've been too busy to get in to the garage lately.

yes i already messaged someone on ebay for the very thing your saying so this may be the last thing to try.

That fly is probably from the smaller chassis such as TS914. They made and sold a lot more of those models.

thats probably why there is aftermarket for that one and not the set i have.

The 399 was used with chassis 18TS-597, 18TS-921, C18TS-921, H20TS-921, J20TS-921, K20TS-921, M23TS-921, N23TS-921, R23TS-921, I think that's all.

i have to try to get one of those chassis numbers in a sams to see if this fly is electronically usable at all for my set.

Isn't those black and white

well i dont know but judging by the size of the fly and the taps im sure its color, but i really dont know.

The TS921 chassis is the last mostly tube color chassis Motorola made. It's simular to the TS914/918 series. I think the reference to the TS597 was a mistake, as all Motorola color chassis were 900 series.

well mine is a ets908 so i still dont know at this point how to identify the fly i have unless i find a sams folder on a set that uses the fly i have and i know there is no guarantee that the circuit will be close enough to use in my set. unrelated but an rca fly 126333 is this a number worth holding on to, i have a line on 5 flybacks 2 zeniths,1 rca,1 ge, 1 panasonic.

The fly in question is for the 19 tube newer model set that uses a feedback type HV regulator. I looked at both SAMS, and there is too much difference.
The other flys in question, it's hard to say, what's useful and useless.

are your referring to the motorola fly being to much different, if so oh well if i dont succeed i must try, try again,lol,lol. well what the heck this set will only be on maybe an hour each week or so, so at that rate it should last a long time.its all set up and it does have a nice picture but not being able to have the bright all the way up and the left side of the screen being like there is a huge magnet twisting the image. when something runs into the path of the left corner then you can see it and also on the cross hatch pattern, all twisted. if i post a picture everyone would probably say its fine leave it alone, so i will at this point.

I've got a big-ass Motorola book with all schematics and parts lists covering everthing from the 19" roundie thru at least 1970. Here's what Motorola's original numbers are for flybacks....

24D67564B06 complete fly
24D67565A05 windings only

wow thanks thats some list or rather book you have.well i was told that this fly i have is used in a few chassis and it looks like the 918a and 914 because moyers tells me that the a07-a06-b06 fly number on the end of the fly number.

I would think that several of those Moto numbers cross over to the 399. Kinda funny really... some of those numbers are quite specific... only for certain chassis coded a certain way, or only for specific models using that chassis... but yet an aftermarket replacement would be will be the 399 for a good many of them.

i just wished it may have worked in my 908 set but i guess i have a nos motorola fly same as fly 399 that will sit in the closet with other old stuff and collect dust,lol.

thanks again for the info i just got my emails and i didnt know it was you that posted the info. i forgot to add that the number printed on this fly dont have the D after the 24 but at the end of the part number there is -185. 2467564a07-185 but no D.

My family ran one of those sets for a solid 10 years. I was repairing Tv's at the time, but I had very little exposure to working on that model. The ETS908 was the last run of that model. Probably the most reliable set at the time. I just looked at the schematic and found it to be extremely complicated, compared to a lot of the other makes. Just hang on to it. There's not a lot of them around.

well you know i am an auto tech and do this tv work in spare time and i thought the same of this set being complicated to but then again i dont have all that much experience with them. ill hold on to it since it does work well and the crt was replaced in 1980.
