I see many analogies in construction to my amplifier. I think the version in the museum is more modernist, i.e. younger. The F443 pentode appeared in 1930, and in 1933 its successor, the F443N, was produced. So I assume my amplifier is from 1930-1933.
If we are dealing with very unique devices, the question always arises about the sense of renovating such a piece. This is a difficult topic to discuss. I collect old TVs every day. I like it when their screen lights up, but I decided to leave some models without repairs. The Danish amplifier will probably remain in pristine condition. I will only try to prepare an electrical diagram.
