Mike just to clarify what I was saying on my readings. First voltage readings were across the shadowgraph wires. The stronger the station is tuned in the less voltage there is same for current. As I move the dial off the station the higher the voltage goes. Same for current. Current is read reming one wire from the shadowgraph and connecting the amp meter between those points.
To answer your questions.
>>>Does that mean that slow change is only when you de-tune from the station? Yes that is what I was saying.
>>>ALso, "off station" means "not tuned to the station" and "on station" means "tuned"? Yes this is what I was saying.
As for changing the 6A7 tube I had tried another one previously with no change. So I robbed one from a Philco 60 and that has made the difference. Seems to be responding in a timely manner now. Strange thing is the other tubes test about the same but slightly weaker but still reading good on my tester. The one using now is slightly better. So I guess we can say the problem is solved.
