My former college roommate is still using his HK receiver he bought used in 1975! The solid-state Citation 18 tuner is very well-regarded. The Citation I and II are beloved tube classics, the 14 is a decent tuner and the 22 is a good power amp. The Citation 23 can be a great bargain for urban use if you get a good one. The 12 and 16 are good subwoofer or low-frequency amps but not up to current standards. Have fun!
