We all know what it is about that model, plus please consider its condition and the fact, that it is not only the player, but also power booster.
Basically you buy all what you see on the pictures (including documents / papers).
Please note that player is located in Europe.
It was installed in my classic car and radio was working great till I remove it (I am bit conservative regrading classic cars and I wanted to have original radio for my car). However I was surprised how good the radio sound was (I think thanks to the power booster) I was not using 8 track player, as I had no 8 track tapes at this time, so I can not say it was working, but again looking to the condition of the item it should work - check the pictures at the google drive link below.
Today I have the 8 track tapes, so if someone is seriously interested, I can connect it and test it.
