You're quite welcome... for grins, I poked around a bit more and found the *actual* issue on a very interesting site that appears to have tons of the magazines that some/many here might remember.

I think they were 4BE6 and 4BA6, or 3BE6 and 3BA6. They could have used one of the TV IF tubes as the AM IF stage, like in an AM-FM set. And some TV sets used a pentagrid tube for sync circuit work, and with some switching that tube could be used for the AM. Though it may be too much switching.
