12:30 "БДС" on the motor – Български Държавен Стандарт – Bulgarian state standard. Unless the abbreviation meant something else in Russian.
I'd love to see a breakdown of how that motor board and motor work.
It would be very interesting to see some Soviet-era HiFi equipment, given the build quality of that cassette plaer.
The motor is marked with Bulgarian state standards abbreviation 🇧🇬. Probably manufactured by the disk memory devices factory.
Jste začal brát piko? Nebo proč je to takhle divně zrychlené?! To se nedá poslouchat. 🙁
great video. This vintage stuff is very interesting. And there's not a lot of content related to the soviet stuff in youtube. keep these weird eastern devices coming up!.
Please more repairs of vintage stuff. 😊
Vintage is best.
weirdly I'm a huge fan of soviet electronics 🥴 Can't explain it myself
23:47 the motor driver is so interesting, i can recognize on the right a speed feedback and i believe that the winding on the left (the one on the adjustable plate) are determining just wich transistor switch on for the 3 phases so a sort of position feedback, seems to me that the speed feedback circuit is changing a bias for the position feedback and probably it result in a current regulation of the motor… Just crazy, so complex and jet simple, if we think that today we use encoder and microcontroller to drive 3 phase motor, i believe no one today would think to an analog way to drive this kind of motor.
I love those things and i love your video Mr. Diode, keep going like this!
There is no radio!? And there is no more ,, r u kidding me'' : )
Appena hai detto motore ac con inverte mi sono eccitato 😛
More😊
Nieyce! 👍
Tak toto je mega! Trojfázový asynchrón na sovietskom magneťáku! Čumím 👍
I'm excited for the BM365. I wonder if it actually needs any service to get it to work. These old Tesla machines are quite well built. From my experience, they almost always only need to have the paper caps replaced and afterwards will work just like new. I haven't had the need to replace any smoothing caps in mine as they are great even after many years.
Just curious, do you know russian? If yes, where you learned it?
That motor is definetly bulgarian make(бдс eg bulgarian national standard) and I suppose it was meant to be used in bulgarian made hard drives, so they just repurposed it to this tape 🙂
Proper calibrated fuse…
Wow very nice explanation and nostalgic video of a tape recorder repair!👍
4:08 aw man the times when i used to shove pieces of napkins inside those holes to record on protected cassettes. Good times.
Hello, I really appreciate the videos about older technology. I feel like these is a lot more to learn, and the video is more interesting to watch when the old-school analog circutry can be explained, rather than it being one chip doing everything. A good example was the Soviet TV series, my personal favorite of your videos, you've taught us a lot about how it worked and that made the videos really fascinating.
Thanks for reading and take care.
