I just got a 680 and I want to preform this mod. I have never soldered any electronics before, but I'm not afraid to try.
What size/gauge/type of wire should I use?

Reviving this thread in regards to DT610
It looks like there's no seperate tape deck circuit as in dt680. I'm thinking if attaching to pins 5,6,7 to equalizer circuit, w303. Any dangers or voltage issues that might occur?

Hello! Sorry if I revive this very old.
Just one question brother, is it just soldering three cables?
I think I will if it's just that. What caliber cable are you using?
Thanks in advance!

Just go to first page of this topic and you find answer of your questions...
The guy doesn't say what gauge of wire to use.
Okay thanks but, i see one little white cable, it's right?In the first post has 13 steps, as well as lots of pictures. they clearly show what cables are used - quite ordinary.
With the right tools and skill - this mod is done in about 1 hour.
is it a bridge or something?

Both connectors need a ground connection, so once the ground wire is attached to one channel, a short length of wire is connected across to the other one.

I'd be highly curious if this mod is exclusive to Panasonic boxes, I have a Sony that I would love for this to work on. Nice work!

Of course not, as long as you can figure out the right place to tap into the audio path.
It's been 9 years since this thread was started. This definitely shows how good and reliable dt680 is. It could last for a lot longer than we can imagine. I have been in the hunt for this box for such a long time and finally got it just recently with the tape decks not working. I was able to fix tape 1 and it's working perfectly now. I might try fixing the other deck but for now I added line in. I followed James instructions (thanks James for sharing). Now I can hook up a bluetooth receiver or crhomecast audio or anything that plays music. 
Thank you eveyone for the inspiration to make this mod despite all the wide selection of bluetooth speakers in the market today. I just love the look and sound of 680. Classic..

Classic..I just had a funny feeling about why Panasonic did not include line input for DT680. I might do a silly thing like connecting the CD Out to Line In. LOL
Hi everyone, few months ago I acquired a RX DT680 in good conditions and fully working (no remote) for little money and performed the line input mod using a 3,5mm jack socket. It works well but with the Lan player I use for testing my units I have to lower its output level, otherwise the sound is distorted. I wish to ask you guys if you think it's possibile to lower the level input by using small resistors between the input jack and the pins to which it's connected and, if the answer is yes, which ohm value. Thanks a lot!
Just a note to say thanks very much to OP for this guide. The CD player on my unit has been dying a slow death, sadly, but I successfully completed this mod last weekend despite pretty iffy soldering skills, and now I'm getting a lot more use out of the boombox.
Still a little sad since I originally bought this thing for the express purpose of playing CDs, but it's still nice to salvage it as a music player. Maybe one day someone'll make new lasers compatible with old stereos. Anyway thanks!!

Thank too much to this post . I appreciate your post .
I don't have lot of experience . But my questions . If I use blutooth unite in line in .
How can I give the blutooth unite power ?
Is this method better than connect to casset head ??

I made a successful mod for Panasonic RX-DT610. I tried some things and found the best place to connect an AUX is at the input switch IC301. It sits between the tape pre-amp and the main amp. I also tried to connect directly to the pre-amp outputs, but there are some resistors in between the pre-amp and the IC301, which makes it such that the signal levels don't fit well.
Remove the front, the control button pcb and the tape deck mechanics. Then, for connecting the AUX to the tape deck signal, connect to IC301 and left goes to pin 1, right goes to pin 11 and ground goes to pin 7:
I also took some pictures for what it looks like in practice, I directly soldered it like this with the main pcb still inside the case. It's hard to properly see, but here's the picture:
I used a 3,5mm jack, which can fit next to the RCA and mic connectors and it's possible to drill without any more disassembly. End result is like this, not the nicest job but works for me:
That's all, hope someone will find it helpful
