Ok this thing is running me ragged did an alignment several times have no problem picking up the signal at 456, 600 and a little weak on the 1500, while playing with with the Ifs A,B,C &D I get decent response H&G don't seem to do much and J is very sensitive, Right now I'm at 620 no station have about 6.5v on pin 3 and the eye is almost closed, if I move to 680 a very strong station the eye is half open and about 3.4v on pin 3.
Should I put the 1meg resistor back or leave the 680k in?
Just to make sure I'm doing this right the first step calls for .5uf in series SG with the grid cap of the 6A8?
and Rec. Ant. Post is the ant post in the back?
Also should Z & G be shorted together?
Thanks
