CTC-12 IF alignment

[DaveWM]

I plan to go back and try a few more things to see if I can get the AGC voltage down with a normal level signal. This set is really just my learning set so I don't mind if I mess it up a little while learning.

interesting, do these sets really drift that far off? I know the coil forms can Change shape and create havoc.
I know the color sets are really tough to align.
all the broadcast Equipment I have worked on there has never been a problem
with encoder's, or monitor de-mod, till I started this 21CT55 project.
good luck!! the i.f peaking is what I am mostly interested in..

I think they can drift, how much not sure, but I do know that they have often been thru many techs or tech wannabes, so there is always the possibility of diddle stick drift which is my main concern. The BK 415 makes it pretty easy with all the bias supplies and many markers. With practice I am guessing doing a quick touch up will become easy. Of course you have to have a good enough CRT to produce a very sharp pic for it to matter.
