I always wanted to add a 1924 Radiola III or IIIA to the collection. I had no idea the volume on the accompanying 1924 Radiola UZ1325 horn speaker would be at such an acceptable level with only 2 864 tubes and using my AM transmitter. It's the typical somewhat raspy "megaphone" sound of '20's sets, but in that is their charm. The set is very small and light and their is practically no glow of the filaments in the 864 tubes. It's working on it's original audio transformer.
