Thank God you adjusted this thing !
Anyhows if the worms beat with the audio you can tweak
the 4.5 MHZ trap but flag it so you can go back.
Also looks a little like an IF problem so try the 2 4EH7 & 4EJ7
if you got them. Probably a low focus tube & the taps do
nothing. Only a rejuve works but still wont look like an
expensive sets focus.
