Hitachi TRK-3D2H Questions

Hey,

New member here. I just bought my first boombox that I plan to restore/customize and I was looking to see if anyone had any information on this model. I can't seem to find an online manual or source for any info on it. Any help is appreciated. I plan on cleaning the unit, changing the speakers out and connecting a bluetooth amp to play music from my spotify. Thanks in advance!

I also have this unit. It is smaller than a TRK-3d7 (7620), but in many ways similar. So the service manual of a 7620 can be helpful to get a rough idea.
The modifications are also on my agenda and easy to achieve. I did the same with a 3D7.
So if you need some support....
I like this unit, because it is so portable. Frequent-Traveler-compliant
