70's Receiver and/or Integrated Amp recommendations

Hi folks,

Looking for recommendations for 70's Receivers and Integrated Amps that will mate well with my Vandersteen 2C's?  I recently sold my Roksan Kandy integrated and Arcam irDAC as I am getting more and more into listening to vinyl these days. I've been using my old Megatech TT-1100 turntable and it still sounds good after all these years. My 2-channel system is in a second bedroom I converted into a den or second tv room. My budget is $500-$600, but I'd like to use some of that (if possible) to upgrade my TT, but I can hold off on that if needed. I know there is tons of different vintage 70's gear out there and it all sounds different. My biggest requirement is finding the right one that mates well "has the chemistry" with the Vandy 2C's. 

Thanks, 
JSB
