Mike, I had no idea what a RAL-7 receiver is so I did a Google search. I found that it was built by RCA in 1930s, has 3-stage TRF front-end, and a regenerative detector. There is a neat video on YouTube of a fellow administration of RAL-6 which I presume isn't terribly different than the RAL-7:

Shoule you actually fire the RAL-7 up, it would be interesting to hear your impressions of this 75-year old technology in light of what we are typically using today.
