Denon - DCD-620 / TU-710 / PMA-757 / SC-M70 Stereo set - Multiple models

Fixer-upper. For the hobbyist/enthusiast. It needs some love and will be worth every penny.
Set consisting of four (or five if you count speakers as two) parts:

Denon PMA-757 amplifier: not all the lights and selection buttons work, otherwise fully functional as far as I know. The amplifier has a huge number of options (and yes, a phono output too :) ) and is a wonderful collector's item.

Denon DCD-620 CD player: The tray/turning mechanism has a worn plastic gear. The tray currently works well, but it occasionally skips during rotation. This mechanism is easily accessible for removing/replacing the gear; the tulip output needs to be checked.

Denon TU-710 tuner: creaks a bit, I think the adjustment mechanism needs to be checked, but otherwise it works perfectly

SC-M70 80-watt, 6-ohm speakers: newer than the components and in excellent condition. Minor signs of wear.

If you want to be sure, pick it up from me and you can of course also see how it works and which things are not so good.
