if you want circa 70's Try to get an old tubed reciever or amp of suitable power. Marantz, Sansui to name a few affordable brands. Macintosh if you've got a few dollars. Old speakers? JBL 100 , Altec, Cerwan Vega, Bose 901 or anything that sounds good to you. Your the one listening. I still have and listen to my old Marantz 2240 reciever, pair of ESS LS5 speakers and a Dual turntable with a Stanton 681 EEE cartridge. Still sounds great and worth any repair that might need doing
