This is the first time I've actually seen an all-tube microphone mixer, and I must admit that I was really keen to work on it as a source of new knowledge and experience.
This one belongs to a friend, and it comes with some history that just makes it more enticing. It was used as a "portable" mixer by a radio station in the USA, WBUC 1460 kc, which is apparently still active today. It has three balanced microphone inputs, and one balanced output, plus a headphone output with variable volume.
The most enticing aspect of this project for me is the fact that vintage audio transformers are used for all the inputs and the output. These are rare, and modern equivalents are quite expensive, so I'm hoping for a great final result.
The unfortunate aspect is its condition. It seems to have been a DIY project, and quite a bit of intervention is evident, so a re-build is probably a better way to describe this project.
Hope you enjoy it.
