- Notes
- This model "Orpheus" seems to have the same chassis - at least the same tube line up as model 82 which has a record player or changer. The tube 24A, originally called UY224A was available in 1929, like also the tube 45, originally called UX245. Therefore the model could also be from 1929, but not earlier.
