Early in the article it's talking about the Loewe 3NF. I've been wanting one (can't afford it) since I started collecting German radios, with my first being a Loewe Opta Hellas 552WP. I've managed to get 5 other Hellas with the 2841 probably valued the highest ( I saw one sell on ebay a few years ago for $1800). The 2841 is a 1957 mono table top radio with 5 speakers with a center driven horn. It has push pull EL84 and SE EL95 amps in it.

http://www.radiomuseum.org/tubes/tube_3nf.html came about because, from what I heard, the German government was taxing radios according to tube count. You'll see most German radios use multi purpose tubes (ECC, ECH, EABC, ECLL) where ever they can. I just re-repaired a couple of Ward Airline radios from 1938 with almost identical 11 tube chassis. They have 4-76s in each, and have no octals.
At first I wanted to be a ET. Now I are one.
