Harman Kardon RARE HK-20 Mono Amplifiers 6BQ5 Working L@@k SAMS included

  
These amps are working nicely i have been listening to the for a few months in my family room. They put out 20 watts of power. Tubes are 6CA4 EZ81 rectifier, a 6cg7driver along with a pair of 6BQ5 outputs all tubes test strong. These are very rare you don't come across a single one of these amplifiers ever. Now you can have a pair for yourself. They are a piece of audio history. These are the add on for a harmen kardon AX-20 which is a mono / stereo integrated amp. These amplifiers are working and i will pack them really well with planty of bubble wrap. Also included is a sams fotofact.
