Hugh, might that tube have been something like the 6N7?
I, too, would really like to see that article.

There was a QST article about a single dual section tube, ham transceiver. I have it somewhere but don't remember the date, but prewar. It used a more powerful tube than the little 3A5 of the BN-1.
