Another very interesting design from the overstaffed R&D team at Sony. Is it digital or analog? We're just as confused as the developers apparently.

Good video as always. Please do some more Sony vintage. They really went all the way. Thank you can’t wait for the next one

Nice. The only tweaks I make these days are the local oscillator or the discriminator sith a wooden skewer I shaped to fit. We have an fm station at 98.5 I find most of the time the tiniest movement will get everything back to good. Takes longer to look up thesxematic and search ak for guidance. Usually less than 10 mins. Yamaha amps will not auto-lock sometimes or will be off by .1 on the fm dial. I just did a Nakamochi T4A4 wity the same issue. 2 min fix.

I've never seen a tuner like this. Great job.

Good figuring, HiFiEngine lists this tuner 1980-1981.

Great repair, That thing must have 1 million solder connections.

That tuning knob looks like an early iteration of what would become Sony's obsession with their Jog Dial style knobs that would become pervasive throughout a lot of their later electronics.

@@TrevorsBench Being in the US can't easily send you work, you have greatly improved my ability to keep my electronics alive. I am rural so technicians are a bit scarce and not real excited about vintage stuff. Thank you, God bless keep swinging.

Those AM stations that couldn't get written to memory were already stored in another memory slot, I think.

I think it was because I wasn't programming it properly, I should have stored #1 first

Hey Trevor, as there is a digital numerical station indicator, isn't it possible to imagine a switch who cuts the vacuum incandescent display in order to manage its lifetime as well as the power consumption once locked on a station ?

oh i miss the days when the FM band down here was like what you got up there. used to spend hours just dx'ing the fm band.. which is now impossible because every single open spot has a crappy translator station on it (most of the time blabbing religious stuff and the same crap on a dozen spots) ruined the fm band down here.

This specimen never made it to the States, never seen & never seen AM presets for that matter. 1 massive board for a digital analog readout, obviously went thru a flow solder machine, too complicated for what it accomplish's. Long wires you hated come back to haunt you. Why Capacitors just went to hell in 1980 when it comes to reliability is the question.
