Was this Technics set up for Radio or Nightclub?

Sounds like "Let's haggle 'bout dis...." to me....;)

Are the tt's worth it to you?  The mixer is a nice antique, eBay it and give it away if it bugs you.

Don't burn the table with all that laminate.....*ick*

HO.....

1750 (+tax) seems a bit 'dear'....

...but the ’market’ wants Lots for the 25’s....

Go Forth, roll the dice.

(...pick an LP you Hate to test...but you know that, Right?)

Folding table legs means it's portable.  Probably a DJ setup.

I can tell you through experience ,the Technics I believe 3000 from memory,direct drive turntable was used in Many professional radio and recording studios back in the70s-80s. You did not mention which model turn tables these are , or cartridges , 
I used to own  the  classic technic direct drive  turntables with top audio technicacartridge back in the early 80s. It brings back fond memories of  being an Audiophile in its purist form with my Nakamichi Dragon 3 head cassette deck, state of the art in its day.
