ctc12 clone beam current

[Username1]

OH, ok, my mistake...

Timmy, you may have to just make a map with resistance readings like the diagram I posted....
From Bill's picture I can't see all the wires, Only people familiar with this set like you and others
not me know what this looks like....

this is where the blue lead from the yoke should be connected. if it is then fine.

look at the schematic to you see the bottom of the fly, that is the ELECTRIC bottom of the fly. I dont know how to be more clear on this.

well i do understand what your saying but if i move this wire to the bottom then it is now on a tap of the focus coil that dont belong there it shows both in the sams and the rca diagram, so i am alittle apprehensive about moving this wire for fear of burning the f coil or something else. if bill was able to take another pic of the connections on his chassis of the f coil we will be able to see why and what im saying here. obviously you guys know a hell of alot more then me but thankfully there is schematics to try to make sure and this is what im afraid of doing . the only connections on the f coil are 1 2 3 4 is not used and wont have anything on it.

look, you have to connect the yoke blue lead (boost) to the 11.5 ohm lug. THEN you have to hook up the focus coil CORRECTLY.

If you are worried about burning things up, just put the meter in the cathode of the horz out and keep an eye on the current, if it starts to go north of 210 pull the plug. Good thing about tubes is they are not instant.

Quit looking at the numbers on the Sams, hook up the coils ELECTRICLY correct per the schematic on the focus coil the the ELECTRICLY correct fly terminals.

You should be very careful before committing to moving any wires....
You need to get more pictures of this either from Bill, someone else, check
the other tv you have, I got several schematics off the internet a lot of
the ctc 10, 11, 12, 13, 14, 15's look a lot alike in the flyback area.....

this is what im tring to explain the f coil is connected correctly i have went over it so many times now the only thing different is moving the yoke blue to the bottom lug it then becomes wrong as far as the f coil goes, the f coil is numbered and the boost does not show it as on that terminal both from the miller paper as well as the 2 schematics.

the other tvs i have is a ctc15 clone without the tube for a rectfier and the other is a ctc16 clone.

It is NOT connected correctly IF you reversed the fly lugs. the two ELECTRICLY speaking bottom lugs connect to the focus coil (D and E on SB's photo).

You just have to figure out which lug is which between the schematic and the coil and connect it right ELECTRICLY.

[timmy]

so if i am going to put the boost to the 11.5 well then it was correct all along except it was not the bottom, on this fly its the one above that checks 11.5 not the bottom.lol,lol........

i did this already but being this boost is said to be on the bottom goes against what im reading. so if i took the 2 from the fly and reversed them then that would be moving the boost wire to another internal tap of the fly and would leave the terminal in question on the f coil alone, right? it would then be using the 11.5 ohms.

[DaveWM]

look timmy, the schematic says the blue yoke lead (boost)goes the the lead that is the most distant from the horz out lead correct? yes or no?

Now if that is yes and you get 10.5 on one lug and 11.5 on the other RELATIVE to the horz out lead, which do you think is the most distant? the 10.5 or the 11.5?

just answer that, then I will respond with the next in the logical sequence.

I just want to make sure the fly is hooked up right.

Well if your ohm meter has the resolution...

A to D should be higher ohms than A to E

that is one way of identifying point E It has the higher resistance when measured
from point A. See the center tap Point E It's closer to A.

Dave what are you thinking about A to F ??
Would that be the farthest from point A ???

If it's just between D and E then forget it.

.

[DaveWM]

B to D = 11.5 per timmy I think, if so D is the boost/yoke/shunt reg
B to E = 10.5 per timmy I think, if so E is the one that goes to the focus lug 2

11.5 would be farther

[DaveWM]

ok so that is the one that is the boost/yoke/shunt etc..

now the other one the 10.5 is the one that goes the the electric lug 2 of the focus coil, do you agree that it is the next one up (ELECTRICLY) from the boost per the schematic?

do you follow this, does what I say make sence when you look at the schematic now? disregarding the number or physical location of the lower two lugs on the fly?
