Restoration of my Sharp GF-767-H, help needed!

[mrgr33n_]

Greetings everyone.
This is my first post so please do not judge.
I am now restoring my boombox I got from a friend a couple of years ago.
In the first picture you can see it in the condition, that it was when I got it.
Due to the fact that I am an absolute newbie on that whole boombox thing, first thing I did was plugging it in and see what's happening. To my surprise everything works well, the antennas are abolutely straight, lights are working, radio works fine, both cassette-decks work perfectly (as far as I can tell) - simply put some old cassettes in and music came out of that box, nothing is scratching.

Bad things I detected from looking at it: the paper membranes of the speakers on the outsides are torn, the chrome dustcaps in the middle and the "dubbing" knob is missing.
So I started by cleaning it up and adding some dustcaps in the original size:

Looking way better than before!
I don't know what it is, but one can see that the right top-edge is a bit curvy. Maybe I have to take a look whats happening on the inside..

Much dirt was in it, so I decided to clean it up in the first step and to take the torn speakers out.
Now I am lacking of spare parts.
I thought of replacing only the original paper membranes with new ones but they are harder to find than I thought because I want some in a similar color and most are black or grey which would not fit the rest in my opinion.
The speakers themselves are in good condition and working fine

But if anyone has a pair of these for sale in Germany or is willing to ship to Germany, please tell!
Any idea of what those boomboxes are worth today or what I have to do to raise it in value?
Thanks in advance and have a nice day!

All of those speakers used to be black you could repair those tears with regular Elmer's Glue and a tiny paint brush you just apply the glue sparingly and wait for it to tack up then press the tear back together and let it set up once you're happy with the way it looks.

Also many 6.5 inch car speakers fit this box and will improve the sound plus you if you use a coaxial speaker it's a great way to upgrade the tweeters as well.

This product from Amazon worked great for me when repairing my torn speakers. A little bit goes a long way: https://www.amazon.com/dp/B00L8A9YTO

I also used a thick black Sharpie pen to restore the black coloring of the speaker cloth.

Oh wow, I never would have thought that they once were black! What an insight, my mind is totally blown away.. for real though. Colour was fading due to sunlight I guess? That makes much more sense.


Thanks for the tips! I will try my best and keep you up to date.

It's the easiest way to do it . it takes time but it's worth it because the ink keeps the cones from further drying out.
You can upgrade the speakers while holding on to original speakers in case you want to change it back
