Here is a copy of a newspaper page from 1940 I ran across, describing the latest features of the 1941 Philco models.
Although it seems like all the writing was done by Philco's marketing department, there are some technical details among the hype. The advantages of the XXL (triode) mixer are discussed, along with the benefit of two IF stages, and the intermodulation problems sometimes caused by an RF amplifier stage. The beam of light phono pickup is also mentioned.
A little hard to read but interesting nonetheless.
