A few days ago, I had an opportunity to visit the American Museum of Radio and Electricity in Bellingham, Washington. They specialize, as you might have already guessed, in radio and electricity, but they do spill over a little into phonographs and other things.
A guide gave me a complete demonstration of the Ultona tone arm on a nice Brunswick BR-60 Radiola combination unit. They played portions of a Diamond Disc, a regular 78 and a Pathé record for me. Now some of the things I've read and heard about Ultonas make sense to me.

It's not easy for me to find demonstrations like this, but they're sure fun when they do come along. I also got to try my hand at playing a Theramin! I guess I'll just have to be patient and some day get a few more interesting pieces to call my own.
Take care,
