Number 2 actually says digital tuner right under the digital LCD screen and above the electronic buttons.
Yeah the TUNER is digital. Its merely a more accurate way to make sure youre on the right frequency, but the radio signal is still analog.. DA converters back then werent cheap like they are today, theres no way theres a ADA in there for that purpose (Remember how expensive the first cd players were?).. And besides, the radio frequencies arent digital, theyre just radio frequencies, its the control and playback mechanism that determines whether the output is analog or digital.. You capture a radio wave, digitize it just to tune it to the right station, then convert it back again to play it back?? When the Walkman was all the rage samplers were barely 8 and 12 bit (and expensive as all hell).. That wouldve been a pretty crappy sounding radio, cause you can bet it wouldnt be using the 'top of the line' 12-bit/22 (maybe 32)khz DAC like Akai and Ensoniqs samplers were using..
My Roland Juno 106 synthesizer uses a digital clock to control the oscillators in it, but that is still an analog synthesizer. Same thing ashow the radio in that walkman works..
