Classic Harman Kardon receiver, I have tested the unit and powers up but there is hardly any output. Even when the volume is turned up full you can barely hear the output. Sold as seen for spares or repair.

Harman Kardon 630 Twin Powered Vintage Receiver/Amp-Tested and Working. Nice amp/receiver. I want to keep it, but... By the way, they misspelled Plainview on the back panel as Plainviw. I thought that was interesting.

Harman kardon 630 twin power receiver. Works fine and sounds amazing. Has one or two bulbs out. Plays amazingly loud with 30 watts per channel. Very high quality unit for the price. This is one of the rarer members of famous twin power line. Two completely individual left and right amplifiers! A heavy unit, it weighs in at almost 30 lbs. All of the knobs are present and note the split tone control knobs for L & R channels. The original red power button was replaced with a blue commercial quality replacement. Im sure of you wanted to you could install the original again. This one works fine. Also two tiny screws missing from the top front of the case.

vintage harman kardon 630 twin power receiver. comes with the original good-condition wood case, which i imagine is hard to find (its dust on top, not sun bleaching). ive owned this for a few years now, used in my workshop, and never had an issue. may be hard to see in the photo, but has am radio, fm radio, fm stereo radio, phono, and aux as well as various other fine-tune sound options which i never used but they all seem to work. the only hiccup is that i bought it with the volume knob missing - so i replaced it with a wood one that i made, which works fine. im sure you can find an original replacement, if youre so inclined. reason for selling : downgrading to a sonos system, yes i know. collection : se london collection option.shipping : otherwise, £25 u.k. shipping seems fair to have me properly pack it and ship it since its quite heavy. any questions, dont hesitate to contact.
