Magic eye tuning aid.

[kramden66]

i had a Panasonic 23" or 25" table model mostly tube set or all tube ( can't recall if it really was all tube ) that had the blue bars that came on the screen when you pushed in the fine tuning and the closer they got was how you were told you are tuned properly , so turn left or right till you have the bars as close as they will get , this set was junked because it needed an rf tuner tube and thats how i got it.
