Hifi "RATEKASE"

[Radicase]

Hello everyone!
I'm Radicase newbie from Japan.
Recently, I finish one of my project "Hifi RATEKASE".
I customized Sanyo T-4100 Stranger.

[video=youtube;WVM0YS_yYIs]https://www.youtube.com/watch?v=WVM0YS_yYIs[/video]

RATEKASE means TV boombox and it named JVC maybe at 30 years ago in Japan.
It powered by Raspberry Pi + Hifiberry + OSMC + Tripath class-T digital amplifier.

I'd like to show how to build it!

Welcome Radicase

 

[Radicase]

Thank you every one
I'm happy to watch my post.
I'd like to attach many photo with text, but I confused and maybe I need to training right now.
But I'll post the many picture.
It is much better to explain than my poor English

Are those 4x6" woofers? If so, Sinuslive SL-150 could be a nice choice, if the magnet isn't too big. I am not sure, but I have a feeling that I've seen also a version with neodymium magnet, that has the magnet on the front side.

At some point Sinuslive had a 2-way component kit with Neo 25s tweeters.

Some random shops that have those:

http://www.carhifi-profi.cz/reproduktory-do-auta/00046-sl-150-neo-25s.html

Visaton FR 4x6 X could also be ok, its a dual cone driver. Though it has much worse sensitivity, 87dB, as the SL 150 is 90-91dB. This woofer can't produce much bass either.

TangBand has two 4x6 models W46-1316N and 1316SM, but they have a more "square" oval shape than conventional standard size and probably wont fit. They also have very low sensitivity (85-86dB) but high power ratings.

Thank you for Questions

Can you recieve live television broadcasts?

Yhank you Martin123,

It can't recieve TV broadcasts in Japan.
In Japan, TV broadcasts is digital wave, and it protect with "B-Cas Card".(I'm not sure what?? and I'm not good at TV )
So, Usually I watch You tube or Vimeo or listen to the music by network radio.

Nice job done, Radicase!
Thank you for sharing more pics.

Thank you Mystic Traveller,

I'd like to share more pics another project , I'll prepare

Thank you Line Out,

Thank you for your adovice!!
I'm not sure about the speaker! And I'd like to know such kind of information

 

[goodman]

thanks for the photos. If I understand correctly:
You use only the speakers from this boombox. Radio and cassette don't work.
Raspberry computer connects wirelessly to the Internet.
Sound is from new amplifier and old speakers.
Monitor is connected to a combined 3.5 mm audio-video output.
Use remote control for all functions.

Thank you for question, goodman!
Yes, I use only speakers from this box.
Monitor is connected to NTSC 3.5mm audio-video output.
However,OSMC can't control hardwere digital volume with Hifiberry.(May be)
Volumio Hifi Music Player can control hardwere digital volume from the browser.
At first, I start with Volumio Music player, but monitor view is very poor.
And recently, I find the OSMC support the I2S DAC board like Hifiberry.
So, I replace the "Cont" variable resistor for volume of Digital Amplifier.

And if it connect to the HDMI TV, It can control TV Remote, but if it use the NTSC
Monitor, it can control only from Kore(Smartphone software).

Also I owned two more Stranger.
One is repaired and all function is working!
