For a superior superhetrodyne circuit for an AM radio you need six 
transistors (could make a cheap radio with four, actually can make a really 
cheap radio with none...). More meant one of two things:
1) had dual conversion (good for short wave), separate oscillator circuit, 
and/or a push-pull final amplifier stage to drive a big speaker.
2) pure marketting (often the transistors which were dirt cheap by the 60's 
were just used as diodes to increase the count.)

I would have to see a schematic to tell which.
