zenith flyback ID

[timmy]

well i have another flyback but again dont know what it is from,round screen or otherwise maybe someone out there knows? the number is s-90526 and comes with the anode wire and rectifier tube socket.

Let's see, that crosses to a Thordarson FLY-408. Looks like chassis 12A13C52, 25BT22, 25CC50. A little tricky to look it up in reverse like that for the chassis numbers (and there were some production changes along the way) but maybe that will get you started.

[timmy]

would you know if this fly came from a round screen tv or if it could be modified in some way to use in a ctc15 chassis?

[ctc17]

NO. thats for a early 70s Zenith 25xxx22 true 25 inch hybird set. Zenith and RCA designed there parts to be almost compete opposites.

We have successfully subbed flys between rca style chassis and clones. I would call it real advanced delicate work.

Best to keep your eye out for a FLY277 and have a big open wallet when one shows up.

[timmy]

ok ill watch, and mine has a fly 273 and its a ctc15 as well so would the 277 be for a ctc 15 or another one.

[ctc17]

FLY273 is for CTC12

Maybe if you get some Ortho fly paper from Home Depot and wrap you current flyback it will clear the shorts out.

[timmy]

well the fly thats in mine is marked fly273 and its a ctc15 and the set works, but what could be different between the 12 and 15?

[ctc17]

why do you think its a 15?

If it uses a 6DQ5 its a 12.

[timmy]

its marked on the chassis and the number matches the sams.

[timmy]

oh wellit does use the 6dq5 but the numbers match for a 15,lol,now im confused.

[timmy]

looks like your right the 15 uses 6je6 and the base is different then the 6dqb, the pins wow it is a 12, unless i am reading the sams wrong, 528.61115 is on the chassis and others on the sams with 611110,11,14,15,40,41,44,45, and 528.61280 i thought the 15 in the chassis number said it was a ctc15, maybe not so then where does it say ctc12 because it is not stamped in the chassis.

[ctc17]

Is this a Sears Silvertone?

[bgadow]

This Sears set was not made by RCA, it was made by Warwick. In some cases companies bought complete chassis from RCA but my guess is this was built in the Warwick factory to RCA specs, maybe with some differences? I doubt it says anywhere on it the RCA chassis that it is designed after, unless RCA built it. The '15' in your model number is likely just a production change number.

[ctc17]

LOLOLOLOL That why he thought it was a ctc15!?!?!?

I have a 528.525 and it is a RCA sourced chassis for sure. The EIA numbers give it away. Everyone here though it was a CTC11

Well that would explain allot.
Your sams should be 655-2, what sams do you have?

[timmy]

that is what i have number 655-2 and it also has the model number of the set i have. and yes sears silvertone.how do you tell by the numbers that its a ctc12 or anything else, because the 11 uses the 6dq5 also.
