If you're not familiar with it please have a quick Google - these are one of the few ways to have home-grade HiFi equipment in your car from the pinnacle of Nakamichi. This is a Japanese unit so please keep that in mind with the available FM frequency ranges. I hooked it all up to bench test and all functions work as they should.
I tested all inputs/outputs/faders/balance/tone controls. Things to note in regards to the condition. Fader knob (surrounds volume knob) is sitting loosely, it still works as it should. RCA outer contacts are missing from two RCA jacks on the pre-amp. This is for the connection to the head unit to transmit the AUX1/AUX2 jacks up front if needed (there is also an AUX2 input on the pre-amp and you can switch between them).The video showing the test is using the front AUX input plugged into the RCA inputs missing the outer contacts - no discernable sound change or issues with them missing as they would ground to the head unit. The photos and this video were taken within the last week. The item "Nakamichi TP1200 HiFi Vintage Car Audio Head Unit/Pre Amplfier Fully Tested" is in sale since Thursday, October 1, 2020.
