Hello everyone,
 After our move to Florida, I'm finally getting back to my radios and of course I've run into a problem.
Its A Zenith G725 AM/FM. I did a recap, checked all resistors and replaced any out of specs, tested the tubes and replaced 2. I did an alignment also. Everything was fine for about 2 days. While the FM works fine, as I was listening to the local AM station it just stopped receiving. I am now able to pick up only one AM station and it's not the closest to me. BTW, I re-tested all the tubes and they are OK.
Does anyone have any ideas as to what happened? 
Here is the schematic:  Zenith Radio Corp.: G725 (nostalgiaair.org)

It's good to be back,
