No Marantz amp ever used the 12B4 input tubes or drivers. Marantz utilized 12ax7 and 6cg7 in the Model 2 and 6BH6 and 6CG7 in the Model 5 and 8B
12B4 is a medium mu triode which was used in tv sets for vertical deflection circuits
Tubes like the 6FW5 and 6FL6 were sweep tubes in horizontal deflection circuits for tv with significantly higher current capability
All of these were used in Futterman output circuits.
