Altoparlante prodotto su licenza Magnavox. Il nome "Mastini" indica il proprietario del brevetto di cui era provvisto questo modello. Si trattava di un meccanismo per il funzionamento a moneta, visibile nelle foto. Spesso venivano modificate per usare due distinte valvole raddrizzatrice e finale in luogo della multipla RT450, divenuta con gli anni di difficile reperibilità. Lo schema riporta valvola R450 anziché RT450.
Speaker built on Magnavox license. This model was often provided with a built-in mechanism for coin operation. Most of these radios were later modified for using two separate rectifier and output tubes to replace the multi-function tube RT450 (a scarce tube because it has been built just for a short time by a single maker, Zenith).
