It is better to buy a Samsonite Fiberglass luggage box and put those components and speakers there. Opening becomes so easy! Can put a battery pack, and all goodies in it.

 

It will transform to an  AIWA wheelie! Spins too!

Update, sorry about the hijack of the thread, the box came apart just as the photos showed. I bent the tabs back on the pot and desoldered the 3 pins to remove the guts. I think things were just a little covered with gunk and I took a strip of paper and placed under the wiper fingers and turned the shaft back and forth and repeated holding the paper so it moved with the finger to clean off the board traces. The paper was black both times. Put a meter on the pins both ways and didn't see any big swings so back together it went. The tabs that held down the shaft flange were a little loose when I disassembled, so I made sure they were down tight. The knob play went away and so did the volume problem. Not sure I'd tear apart again but I really like the box and it catches everybody's eye setting on the desk. Lots of comments. Was glad to plug in the new walkman to it instead of the computer speakers I was forced to listen to while she was down. A big hats off for the help on this everyone!

As a lot of you know I recently purchased a TDK 2 speaker boombox that had a wonky volume knob. The pot itself was wiggly and the switched "on/off" part of the knob didn't work so I had to unplug the box everytime I stopped using it. I purchased a replacement volume pot/circuit from someone on ebay to swap out with my broken one thinking it wouldn't be too hard :lol: .


So, not knowing how to open the boombox, I asked the ebay seller that I got my parts from :thumbsup: . If it wasnt for him, there is no way I would have got into it. He gave me some great tips.

These steps are for OPENING THE BOOMBOX COMPLETELY! If you need to remove just the speakers, follow steps 6 & 7

1. remove handle allen bolts
2. remove strap bracket allen bolts
3. remove side plastic trim that curves around to the bottom with allen screws
4. pull the volume knob away from the face and wiggle the LED circuit board from the knob
5. pull the selector knob away from the face while wiggling it - there are little clips that release
6. pull the decorative rings off from around the speakers
7. remove the 4 phillips screws holding in the speakers, pull the speakers out, and slide off the quick connectors,
8. you can see 5 more screw holes that were buried below the lip of the speakers, inside those are more phillips screws


this is where it gets tricky...


9. to axcess the other 16 screws you have to pry off the shiney black face of the boombox
10. gently start wedging something behind the plexi at a top corner
11. use a hairdryer on hot/low to soften the double sided sticky tape that holds the plexi on
12. work slow and carefull all the way around the boombox to pry the plexi away from the front case
13. once the plexi is off, set it aside face down so you don't accidently stick the plexi to something
14. remove the remainder of phillips screws on the front case (1 is extra long top center, a few short ones on the bottom, and the rest around the perimeter are all the same length)
15. if you look behind the left speaker you can see a gray ribbon band that tethers the rear case to the front circuitry - pull it out of the connector on the front side of the case
16. the top and bottom of the boombox has rubber stuck to it, pull up the rubber just away from the front side of the case
17. pull the front of the case straight off from the rear side
18. there are still some cables tethered, but you should be able to work from there



GOOD LUCK!

 

 

Thanks for this guide! You're amazing!!

I would have smashed it and took a video of it on fire!

I still might. My cleaning only lasted 2 days. It went back to the same crap. I think I can find a new pot. I did some looking and found the same style just have to take apart all the way (removing the entire pot off the board) and verify the specs. Only took off the top section before.
