Pioneer SX-3600 in almost mint condition cosmetically and works great!

I usually service and upgrade most the stereos I get, but I have a pile up right now so I don't have time. This unit is super clean both externally and internally. The only thing wrong with it is the speaker A button doesn't stay engaged when pushed. The speakers work but the button doesn't fully engage. Probably something simple, but I have other stereos to work on. I did flush some deoxit into the balance and volume control, but it could probably use a more detailed cleaning. Phono was tested and is working as well. 

God bless!
