The PAM-8603 would have been sufficient, and cheaper. Good video, visually, but not very clear WHY you are doing some of what you do. 1) Why transfer an old capacitor to the power supply? 2) The old VU meters, what did you do and why? 3) If the old circuit board and cassette mechanism are not used, why not just remove them and make the speaker much lighter? (Any other switch would have done the trick, using the mechanism wasn't entirely necessary.) These are all things that your viewers would need to know if they hope to attempt such a mod. Or at least if they expect to learn anything from your channel. Any insight into your thinking process would be a huge benefit to them. Indeed, I wouldn't call your video a "tutorial" without at least SOME play-by-play instructions. No need to speak, just text will do... like you did with the parts. Or even a few paragraphs in the video description. TE, please do not take this personally. I mean it as constructive criticism to improve your videos. I, myself, do not need you to answer these questions (except maybe the first one), but many would be more confident to try mods like this if they had more information. Cheers!
There are some poblems with this 'setup'. Your device suffer with a ground loop (jittering noise). Install a 1W isolated DC/DC converter on the bluetooth module. Also install some buffer caps on the amplifier otherwise the amplifier can die very soon (there is a huge power dip when starting). I don't understand why you didn't use the internal amplifier anyway.
Would it not be easier to just use a small reversible ( send or receive) Bluetooth transmitter such as the ones used on a non Blue tooth TV to transmit Blue tooth to Bluetooth Headphones etc , connect it to L&R Audio in or L&R Mike in, set it to receive Bluetooth from your mobile & off you go
you could have connected the bluetooth module to the radios inbuilt amp through aux +5v could have been used from the boarditself it uses +12 volts for the motor these old sets have great sound would not have do do so much modification

EDUARD BALALYKIN ну ты и лошара😂😂😂😂😂 а я со своего SHARP 777, подобную приблуду сделал, только ЛПМ выкинул, и вместо него модуль AYIUMA c mp3, flac, mp 4-5 вставил. Лабает огонь, на даче самое то😜😝😜😝😜
Si, buen detalle, nada erlegante de su parte para presentar este proyecto. El lo que hizo fue poner a funcionar los parlantes separadamente de la grabadora como tal; le instalo el modulo amplificador con el modulo bluetooth y listo. Pero si, comparto tu inquietud.
@@osmosis3182 bueno amigaso, no era para que te pongas mal, el trabajo quedo muy bien y funcional que era lo mas importante , muy buen trabajo, pasa que veo gente que los limpia y los deja como nuevos. Pero igual excelente trabajo el tuyo. Saludos cordiales.
Exactly what I was looking for, using the original hardware as much as possible. Thanks!
look this video it´s more complete

Thank you very much! You're right
Why more power than "necessary"? More control and better sound when you don't have to push the amp to it's limit. 🙂👍
Excelente trabajo, con esa adaptaciòn sigues disfrutando del radio reproductor portatil...!

Felicidades buen trabajo y muy bonita radiograbadora. Saludos.
I wish you could show where you got the bluetooth connection and where you connected it.
Simplest way is, buy a Bluetooth transmitter at 30 bucks which has a 3.5 mm jack and fit in the phones socket of cassette player . done !!!
can you create a video out of that idea
I found a usb Bluetooth receiver
You mean BT receiver? The transmitter is the mobile phone...
Ótimo som e ótima montagem
mini tutorial muy bueno, le felicito al autor desde España.
new subscriber good work
nice and clear bass from 2x3watts RMS speaker
thumb down for the VU-meters put in paralel with the speakers
very goog me gusta like
Hi nice restoration.
What is the purpose of the Diode on the Meters negative poles at 4:12?
This is not restoration.
This came out good

Hey! If you put a toroidal 14v, you gain double power minim 9w ×2. I own this boombox. The tweeters are missing from inside!?
The amp is just distorted.also you have a ground loop .you can fix that by installing a ground loop isolator .
Where did you get that?
Mình cũng thích loa, với caset cũ các kiểu nên mình sub kênh của bạn
What the hell ? This is not PERDISCO. This is HITACHI ! I have it too ! Very good cassete player !
Perdisco is also Hitachi

Fantastic video again my friend. Love and light. Paul.

@@RanjitDas-hs1cv what is radio name
if the old unit still working,radio,tape just connect the bluetooth module to pre amp where tone control before located
The old unit is not working 😂
Nice job.
bạn nên làm trên con đài sony nhé, trông con đấy có vẻ ngầu hơn ^^
Con này có 2 cái kim VU vẫy kiểu cổ điển nhìn cũng hay hay (^_^)
I don't know what is the use of pam8610 amplifier board in this project?????
Yes, he´s working the module bluetooth and the amplificator separatelly of the recorder amplificator.
A bluetooth aptx module would perform greatly!
Congratulations
Bắt đồng hồ vumet song song với loa ( kênh ra 3 w ) thì cần tụ mấy mf vậy bạn
Cái đó mình cũng không biết. Nhưng theo mình thì nên mắc nối tiếp VU với 1 con điốt và 1 cái biến trở, đó là cách mình làm trong video.
Nicely done...
loved it
👍
Very Good Idea !! Like !!
First !!

I would just connect an Bluetooth to the back of one of the input connectors?
Thich lam .day nghe ket noi di a

I’m too lazy. I’ll just buy a Bluetooth speaker and be done
Super cool! saludos de un Colombiano

Thank's bro! It was broken and I did not know how to fix it, so I had to do it
Mạch Bluetooth mà bạn dùng nguồn riêng 5v là không còn nghe è è to như vậy chứ để 7805 dùng chung tạp âm rất to
ừ, có lẻ mình nên sử dụng mạch kết hợp bluetooth và công suất chung trên 1 mạch sẽ ổn hơn
Nicee. Very good
Nice
Loại máy này vào những năm 1980/1982 hồi đó gọi máy loa liền.

Where do you buy that boom Box
Как правильно изуродовать мафон
I wish I could do this. I have a vintage boombox I wanna add bluetooth feature
Music please
5w x2 only, the bass is hight for 5w speakers 😱
good
Avoid noise from the sound...!
Where I buy to this set
I bought those here: linhkienctn.com/
bạn hướng dẫn tận tình đi, mình muốn làm lắm mà không biết nối dây vào đâu, mình xin bạn đấy, mình cần làm ,cần lắm
ma nghia dễ mà
Dễ lắm bác, bác mua cái mạch thu bluetooth có cả amply trên đó, nó có 4 dây ra cho 2 loa. Bác hàn 2 loa trên đài vào đó là được.
Đài những năm 9x giống nhà e quá
Tiếc là nó bị hỏng nên không dùng được mạch âm thanh của nó

Nghe cũng ổn bác à, chỉ có điều lúc mới mở lên nó nói "bluetooth mode", tiếng đó quá to, làm giật cả mình, rè cả loa

Or the Bluetooth module
Because the two modules share the same power source, there is interference. You can fix it by using B0505 power supply isolation IC
