I would typically stay away from AIWA stuff especially from the early 2000's. Aiwa was the low cost Sony when Sony was already cheapening-out everything. MD drives are mostly a hit or miss, it is very hard to resurrect a non-working MD drive, also because most of the time it is not clear what is not working. On top of that, they were designed as consumable, use it until it works and then replace it as a whole or buy a new one.

[@johncoops6897]

And furthermore, why would _ANYBODY_ want an MD player anyway?

[@dlarge6502]

@@johncoops6897 Because MD's are amazingly cool. I use MD vs a portable CD player. And no, dont mention mp3 players. I was against them when they came out and still barely use them. And no, no I dont use the phone. The phone is a phone and a convenient camera for when I dont have a real one and portable web browser. Thats it. I tried playing a podcast on the mobile once and the built in app was crap. It was impossible to control the playback, it used the same UI design as sound recorder on win 95 omg.

It was listed on FB as "Made in Japan" but it was actually made in China for the Japanese market. I wonder how many years that linear power supply spent working on 20% higher voltage than it was intended for.

[@12voltvids]

It was purchased in Japan.

[@CleoKawisha-sy5xt]

oh its 20% higher?

[@1blisslife]

Watching your video gave me flashbacks of my Aiwa XR-FD55 that I imported from Japan. Taking it apart was like putting together a complete lego set. It has probably triple the amount of screws (more) than what I saw on your video. I bought it because it has MD/USB and VU Meters(my favorite part). I was able to play MD's a few times and then it quit reading them altogether. I always used a step down transformer for 100v & it still quit on me.😢 I've since learned that some of the laser pick-ups do degrade with time on some MD units because of the materials used. I also became a subscriber thanks to your video. That cap tester is pretty cool... I will get one and take my Aiwa apart again to test the caps on it. I'd probably take apart your JVC camera over my MD unit any day! 😂😅 I do hope you can get your MD and that camera fixed. Cheers

[@CleoKawisha-sy5xt]

[@SPINNINGMYWHEELS777]

Cool design except for that ugly volume knob - don't see any MD players in my area ever although I had a few back in the late 90s for capturing field audio (portable Sony recorder) .. and we used them at the local community radio station for the bumpers and produced weekly commercials - we had nice Sony rack mount players - very convenient form for that use and we were all pretty happy with the basic sound quality .

[@Hagis2k]

Interesting I was looking at the design of the top of the unit are AIWA and JVC the same company? The similarities in the design of the UX-7000R is striking, mine has only CD and not any MD player. I also have an old Sharp MD-MX20 which has MD too, and it has some stupid design with a volume knob sliding out and in when you power it, the tray that holds the potentiometer has a line of cogs that a gear drives it in and out and it lost a few teeths before. I made an mold of the gears like 8 years ago and it has been working ever since that up to a few months ago, then it broke again and all parts are NLA so I shall try to draw something in autocad and make a replacement my self.

[@12voltvids]

Aiwa and Sony are related. Aiwa is a sister company to Sony. They often did test market products and offered lower prices products. They had some great products. My first 3 head cassette was an aiwa. I wore that thing put literally when I was making mixed tapes for all my friends. Replaced it with the teac v850 I still have because i wanted dbx. Sold it to a friend that was starting a mobile music company and he used it for years till he got robbed. Was working out of town at his government day job for 6 months. His first wife was left at home and his van with all the gear locked in his locked garage. When he got home all his equipment was gone. There was no sign of forced entry and the truck was empty. Only way to do that was unlock the garage move the van out and unload it then put the van back in. Obviously it was the ex-wife and her loser friends that she was partying with while he was away working. She had a drug problem and he figures she sold all of it to shove up her nose. When he returned he handed her 10,000.00 in cash and said if he ever saw her face again he would have her charged and spend every last dime he had to send her to jail for 20 years. Made her sign an annulment declaration and she left town never to be seen again. She wasn't too smart, she took the 10 grand and left. I bet there are many that wish they could get off that easy.

[@Vintageelectronics2296]

Dave which do you think is best a Marantz PMD-430 or a Sony TC-D5M

[@12voltvids]

Never seen a marantz. Even the D5M i hadn't seen many. I have serviced more on the channel than i did in the 20 years i was in the biz because i didn't service portable audio except in my last year after my small shit guy retired. I did tv, projection tv, VCR and video cameras. I didn't do much audio unless the helper was stumped. He did all the belt replacement and idler replacements. I was too busy with TV's and vcrs. I think many get the impression that i run a repair shop still and i don't. I take on repair projects but don't do this for a living. What I make fixing stuff lets me go out for dinner about once a week.

That has to be a record for the most screws on such a small piece of equipment, btw the the digital watch,is that an 80s retro, and why wear a metal band when you could short something or yourself out. I had Casio watches like that 40 years ago. Was the motor for the md player working, I would have attempted to check if the coil was open, mechanical error because the motor running would be the next logical step to read the disc and display the information. The switches you cleaned didn’t get all of the dirt and it could be a dreaded ribbon cable that is not communicating properly. One last thing, when were md players in wide use, I never saw one or any of those md discs. The closest was cd singles which would work on a CD player or computer with a cdrom reader. You’re very patient while working with this stuff. I would have walked away several times, so I didn’t throw it across the room

The watch is not a retro. I've had it over 20 years. It's solar powered and radio synchronized to the atomic clock via wwvb radio station.
