My last HK 670 for sale. Very nice Harman Hardon HK 670 AM/FM receiver from 1979. Probably one of the 3 best receivers they ever made. This one has been serviced with DC and Bias checked and set and any soilder joints that were borderline have been reflowed This features 60 watts per channel of high current and has not problem driving low impedence loads. The sound quality is excellent . Nice phono section. The A terminals have been updated for use with bananas but the originals will be included. The original power cord as been repaired as I use a detachable with my gear. The receiver is very clean There are a few scratches on the top side of the faceplate but the but overall very sharp looking . This unit needs nothing and works as it should Asking $175 Thanks,

    Why thank you. No really I sold off my high end stuff 2 years ago to pay the bills and it has been going downhill since. I am trying to find things (sound) I can live with. It is hard to go backwards. I bring things in, compare them to the previous winner and then i must move the loser of the head to head out the door. I cannot even afford to keep two items. Then it never fails once I sort of settle on something another $$ problem comes up (car issue medical bill ) and we start over again. Welcome to the USA in 2013

    SOLD
