| Description |
Since different radio models from 1933 show an AF2 in the papers, we list the AF2 as first series in 1933. Fact is that the AF2 was announced in Spring 1934 but its predecessor, E447 was in those sets from 1933. Only few people know and we would have too many reports saying the tube is of 1933 if we would put it correctly to 1934.
