Assistance with my Crosley 307-TA

What do you have for equipment? A tuner subber could be really handy..

Is B+ around the AGC, tuner and the IF's okay?

Control grid of the first IF tube is usually a good place to input an IF signal.

I won a service contest once by using a .01 uf cap and touching the grids of the IF tubes to very quickly narrow down the dead stage of a raster only condition. There should be some static and noise as you work back untill you get to the dead stage. The coax from the tuner will be a good start to divide and conquer.
By the way, my little shortcut, gave me my diagnosis in less than 10 seconds. I had the bad stage immediately but I had to show I knew how to use the "test equipment" , a VOM. He never seen a finger used as a signal source!
