I am wondering why Philco did this in their late 40's AM-FM, transformerless sets. I was looking at a 49-906 today and was surprised that they used one of these tubes and I have two junker AM-FM Philcos, one console and one table model, that use two of these tubes. Usually these were reserved for portable AC-Battery sets and other than an odd Emerson I used to own, it seems Philco was the only one to do this in their regular radios. Anyone know why? Yes, they work fine, just odd.
