The TP26 is described by Mazda as an economy triode pentode frequency changer for battery receivers for long and medium wave only. The screen current is reduced compared with the TP25. The TP25 has the oscillator grid internally connected to the pentode suppressor grid for oscillator injection and is described for use in all-wave (i.e. long medium and short) receivers. In the TP26 the pentode suppressor grid is connected to the negative side of the filament. The TP26 is designed for oscillator injection via the cathode and an application circuit is given in the data-sheet.
The reverse is plain.
The classic envelope is 32 mm in diameter, and excluding the MO base pins, is 90 mm tall.
