Questions, recommendations re: new to me AU-7900

Hi Everyone!
Could use some advice here.
Last week I acquired an AU 7900 from a friend, no cost. He's had it in his garage collecting dust and thought it would be better off with me. Have yet to fire it up, he said it worked fine last time he was using it. But that was a while ago.

Any suggestions before hooking it up? It does look like it could use a general cleanup
Serial # is 227030316.
I have attached images, hope I got them inserted correctly! One question I have is the 220V tag on the back where the power cord goes into the unit. Should I be concerned that this should be used on 220 circuit?

Not sure what to do with the Sansui, options are, put a turntable and extra CD player on it and use a set of Ohm H speakers on it for another room and/or maybe gift it to a relative?
Still need to test it to make sure it is OK, may have it checked and serviced before I do anything.

This is my current set-up:
McIntosh MC 2505 amp with DB Systems Precision Preamp for CD and 3 MM turntables (Kenwood KD500 and KD550, and AR-XB), then a DB 8HG for Linn LP12 with Dynavector DV20x MC cartridge with Ohm Walsh Series F speakers.

Second room system had a Denon 3300 but it seems to have given up the ghost so am considering using a B&K Reference 20 with a Nakamichi PA-5 amp, speakers in there are DynAudio 72.

TV is using an Aragon Soundstage going to an Aragon 4004 and using Martin Logan Sequel II speakers

Open to suggestions and recommendations
Thank you!

You can change the mains voltage - see the black rectangle thing inside the unit underneath the two large round things, in your second photo above? You need to pull that off (with the unit not being plugged in), and move it to your local voltage.

If it were me I would power this unit up through a dim bulb tester first time - instructions on this site for how to build one - very simple. Otherwise, for less hassle, select the voltage and power her up, connected to a pair of working "test speakers" - ie: not your best pair!
 
Thank you!
I checked that black rectangular block and it is set to 120.
I do happen to have a cheap pair of speakers for testing and will search the site for the dim bulb tester. After doing a clean up inside, very dusty!
