- Notes
- The Marvelo model 30 "All electric Screen Grid Receiver" has a push-pull output with screen grid 245 tubes and dynamic power speaker, which is most probably a moving coil electrodynamic speaker. Order number 201A50101 without tubes is $ 42.50 (List $ 95) and as 201A50103 it is with tubes for $ 51 (List $ 112). We can well imagine that it is selling out old sets from the season before 1931 for other companies. Therefore 1930/31 (if not even 1929-31).
