I think I might have some diodes that might work in this radio, but I'm not sure.

I just looked over at AES and they had 6 signal diodes listed there for sale, 3 of them of the Germanium variety (1N34A, 1N60, and 1N270) and 3 of the Silicon variety (1N4148A, 1N914, and 1N4448) and I'm curious as to which one of those would work best in this application, also I'm wondering where I might find some high impedance headphones like what this would use, or if this might even work with a high impedance speaker like the type used on the old 1920s radios used?
