The hk670  twin powered integrated receiver was harman/kardon's top of the line model from about 1979 to 1981 and was its last with an analog tuner. The original retail price was $550, the equivalent to around $1700 today. It has a dual-mono design; however the single transformer makes the designation of twin powered misleading. The 670 is rated at 60 watts per channel and some sources say this rating is conservative. A fan of the aesthetics of older HK gear, this one isn’t quite as pretty and is a beast in terms of size, yet it still has a certain vintage charm.

This hk670 is a wonderful piece that's really rare and that flys in the face of other "silver faced" offerings from more recognizable brands. It's playing these days with a pair of vintage Alison Model 2 and the symmetry is magnificent. The pair play like they were designed to be a match. Just true and musical in every way. Has been thoroughly gone through and brought back to spec. This H/K is ready to give the next owner years of fuss-free enjoyment.
