well hes only in 2nd grade ,lol,

you have to look at it, I am not there so I do not know, just wire it according to the schematic now that you know the correct lug PER the schmatic. But I would guess yes you need to reverse the focus 1 and 2 since you orig had the fly wired backwards.

so you still suggest using the 11.5 for the blue wire thing? what was wired wrong was the heater connections on the 1v2 originally when i found that mix up in the focus circuit

11.5 goes to boost/yoke and lug 1 of F coil

10.5 goes to lug 2 only of F coil

this is whats blowing me away because this is the arrangement it was befor

[timmy]

yes i think so here goes, the lead that is supposed to be the boost and the blue wire from the yoke i have to put it on the other leg that measures 11.5 and then wire the f coil the right way, which would be just reversing 2 connections on the f coil, am i correct ?

[timmy]

well i have to take a break i need to bring my son to his mom in PINEBUSH.......

I got the pop corn out.


Timmy are you sure you have the lugs identified correctly on the focus coil?
there should have been a paper with instructions on it. generally the 1st lug clockwise of the red dot is 1, then continue clockwise for the rest.

there is generally a ref dot of paint to make sure you have it oriented correctly.

then you still should use the paper instructions, they tell which goes to boost, which goes to the 130 pf cap etc...

[DaveWM]

when you feel like you have it all correct do the following:

Before power up
get the HV prob setup and in place.
have the horz out cathode meter in place to read the current
have the diddle stick in the eff coil ready to adjust
reset the HV pot to mid range.
check for any loose wires or solder blobs
check the wiring again.
have a B+ meter on the B+ 400v test point on the chroma board.

make sure all the cap leads (horz out, shunt tube) are in place
make sure the convergence board is plugged in
make sure the CRT anode is attached and will not fall out from the HV prob.

all tubes in sockets, CRT socket attached, kids/pets all accounted for...

power on:
check B+ should come right up to 400+ maybe spike higher until tubes warm up.
watch the horz out cathode current, should rise to about 200ma, if it goes over 210ma unplug set.
watch for smoke
hopefully you will hear the crackle of the HV and you will be able to set it up correctly with the HV pot now.
