First what ever you do is FLAG you alignment tool with a piece
of tape so you can go back to the start !!!! Write down the turns
CW or CCW as you go. It shouldnt take much, like <1/2 turn.
Traps can be adj with an OTA signal ( 41.25, 4.5 etc)
Now the dirty truth. I was in the TV biz from 1970 til the end of CRT's
I never did an alignment. Only one tech I knew in the area did one
just to say he did. I may have seen ten sets ever that needed it.
A few had a damaged transformer & got eye balled. A few more
got tweaked but not by a tech. A few others were real Emersons
built in the mid - late 60's. Total toilet sets !
good luck
