The Mazda near equivalent is the CME1703. It has a 12.6V .3A heater so OK in series heater chain. First class screen but a gun that went low emission after approximately 3-4 years. Philips/Mullard were very consistent producing an excellent range of tubes but to be fair they had a problem with the heater assembly in the 70/90 degree tubes. A fair number developed a partially shorted heater after around five years use, a fault that never occurred with the AW43-88. John.
