im posting another follow-up, as ive been trying to restore an emerson model
663B.

i found out the weakness of the picture was the ion trap being on wrong.

the picture is now bright sharp and crisp.

everything works now, except for 2 problems. the horizontal is VERY touchy,
and the sound is weak, but i think i know whats wrong with the sound.

here is what i want to try to solve.

i got the set to work fine, but the horizontal wouldnt lock when turning the
hold control.

i went to the back and adjusted the horiz. freq. adjustment and it showed up
as multiple images on the screen, and i adjusted the hold control to get the
picture to lock into place. but here comes the problem:

the control is very touchy, you have to have it dead on to lock. and the
main problem is, lets say its on a scene from a program, and the picture is
locked in place. well, if the scene changes, like if it gets darker or
brighter, or if the scene moves, the horizontal is out again.

i readjust and get it to lock, and when the scene changes back, its gone
again.....

but if i leave teh lock alone, it will lose horizontal, and when it comes to
a scene similar to the one i adjusted it on, it slows down to a stop and
locks again, until the brightness, or the scene changes in any way, and the
horizontal jumps all over the place.

I dont have any trouble with the vertical, its as stable as can be, altho,
there are retrace and forground dashed lines that change at different scenes
that drive me nuts, but ive heard thats from too strong of signal.

Any ideas?

Have you tried posting on rec.antiques.radio+phono ?

Coupla vintage TV guys over there, they might help.

Dan,

The horizontal lock problem is probably the phase detector diodes. Not sure
about the model you are working on but, this is usually two selenium diodes
in a small plug-in package. Could be a tube in older models.

absolutly no diodes.

I fixed it. stupid me, i had the caps backwards in the sync seperator. the
sync seperator tube 6au6, the coupling cap was accidently grounded, instead
of coupled into the sync amp tube. so, there was the problem.

the sync both vertical and horizontal is locked on tight. no drifting, but
there is a problem in the AGC. because when the scenes get brighter, the
picture begins to tear and notch horizontally, like your watching
macrovision, or a scrambled cable channel. but it only does it on bright
scenes. it works perfect on normal to darker scenes.

any ideas?

Does it have an AGC control? If so, does it have any effect? Good place
to start.

nope no agc control.
