This is the Crosley Model 51S Special. It has 3 knobs and 2 tubes. It has a different front panel from the Crosely 51SD Special Deluxe.
Operating instructions (see tech.info) show a choice of completely different tube configurations:
2 x UV201A needs a 6 v storage "A" Battery
2 x WD12 uses 1.5 v dry "A" Battery
2 x UV199 requires 3 x 1.5 v (= 4.5 v) dry batteries plus socket adaptors.
Same is valid for the Cunningham equivalents.
Later models could also use the following combinations:
2 x UX199;
2 x UX201A;
and for increased output power:
UX201A and UX112A
UX201A and UX171A;
UX199 and UX120;
Later models have a terminal to connect a "C" bias battery in case of operation with an output tube of increased power: UX112A (max0.2 Watt); UX171A (max.0.7 Watt); UX120 (max.0.11 Watt).

El tanque de sintonía del 51S difiere notablemente del modelo 51. La bobina de sintonía tipo "spidweb" esta formada por 32 espiras con un diámetro exterior de 90 mm. y cuenta con una toma a las 6 espiras, que va conectada a tierra. La parte de 26 espiras en paralelo con el condensador forman el circuito de sintonía en tanto que la toma de 6 espiras se conecta a la antena.
La bobina de realimentación es similar a la del modelo 51.
