The ETR92
The following year in 1960 the final export set was released, the ETR92. By this time transistor technology had improved allowing an all-transistorised set to be produced, the new Mullard OC17x range of transistors taking the place of the frequency changer valve in the ETR82 model. Bush also took the opportunity to extend the upper range of the short wave coverage a little to 22MC/s (13m-band).
Externally the ETR82 and ETR92 appear identical, they share the same colour scheme and both have built-in telescopic aerials. They only vary in the ETR92's dial having been modified slightly to include the increased short wave coverage and with the ETR92 having the addition of an headphone socket.
Battery supply for the ETR92 was 9 volts made up again from 6 x U2 cells instead of the 9 volt PP9 battery used by the domestic sets. Presumably this was done because U2 cells were more readily available than the PP9 overseas.
