The Pioneer TX-055 FM/AM Digital Tuner: Tastes Like Chicken If Chicken Was A Radio.

[@stuthelotusguy]

Nice unit. I really like the way you present these, well done. On a technical note, these do not use flash, but rather a large low voltage capacitor to store the setting in RAM. The 0.22F cyan one at 7:36 is the one in this unit. Note Farad, not microfarads!

[@AudioThrift]

Right. I just meant it's not on a spinning disc or something... lol That's a LOT of farads. Keep the fingers away. :)

The memory is retained via a super capacitor, if you look near the Toshiba CPU on the left, you’ll see it, the only green electrolytic cap on the board. Fairly common way of keeping a few bits alive back then. Surprised it’s still good after all these years. Speaks to the quality of components used.

[@AudioThrift]

How long can something like that hold on to memory, usually?

Cool digital tuner 👍🏻

Great video - One thing I noticed was that you were getting stereo signals on even integer frequencies (96.00 and 102.00, IIRC). In the USA, all commercial FM stations broadcast on odd-value tenths - .1, .3, .5, .7, and .9. As a somewhat OCD person, this was driving me nuts. I'd bet there's a adjustment pot on that easily-navigable board for adjusting that. I've never done it, I'm only guessing. At any rate, great video. Looking forward to what you have coming up next. Cheers.

[@AudioThrift]

Yeah, I noticed that too... I was able to find the service manual for the 950 which is exactly the same and, if I'm not mistaken, there is actually a process to adjust that but I need a signal generator or oscilloscope. I want to fix it because it was bugging me too. Hopefully I'll get my hands on oscilloscope from one of the estate sales we go to. But thank you. I appreciate it.

Most of Pioneer's mid to late 80's equipment are often overlooked and can be acquired for very little. Their early 80's stereos? Not so much...

[@AudioThrift]

That's a fact... estate sales have certainly taught me that. I don't want to admit how much I paid for the other two Pioneer components I bought...

[@jasonschubert6828]

Really? I have a midrange blue line system from 1981 and it sounds awesome. I actually have it hooked up as a second system on my main speakers!

[@TorontoJon]

LIKE number 1 which is always fun. ;)

[@michaeldina1103]

Thanks!

[@jasonschubert6828]

Judging by the controls on the (matching) amp, I would suggest this system is designed for karaoke!

[@AudioThrift]

Nothing like watching your drunk uncle butcher Hotel California in the living room on Thanksgiving. lol

[@jasonschubert6828]

I would probably be the uncle these days! 😝

[@robertdavis5714]

I actually like that Green, have an Pioneer Audio Timer from that era. Gets Power from 1 of the capacitors, Pioneer did that on most.

[@AudioThrift]

Nice!

[@robertdavis5714]

By the way Nice production, Keep looking...........Keep buying,

[@AudioThrift]

Thank you. I think the production is my second favorite part of the process (after shopping for stereo stuff lol)!

[@robertdavis5714]

@@AudioThriftJust noticed, now that is a score what looks to be a Black face Pioneer SX780. Yes, finding that buy is a wonderful feeling. Wish I could do that camera stuff, turn into a Zombie once I see the light and lens. You do a pretty good job with your acting and trust me I rarely pay this compliment.

[@AudioThrift]

@robertdavis5714 Well thank you. I'll tell you my secret; a teleprompter and a shot of tequila... plus rehearsing it a few times so I get the cadence right. You should see the multitude of bad takes. They're horrible. :P
