Description
HK770 from the early 80s(?) Works perfectly, but being sold as-is for parts or repair, as this is somewhere around a 40 year old amplifier. The cosmetics on this unit are not so good. There are scratches and a little paint missing…plus it needs a good cleaning (inside and out). Near zero dc on the output terminals. Hooked up a music source and it sounded great to me. Meters seem to function properly. Looks like the previous owner cut the power cord and added several feet to it (see photos). I let the unit run for several hours and it worked flawlessly. Let me know if you have any questions about the unit. Will need recapped eventually.
