Harman Kardon CONCERTO Stereo Tube Preamplifier WITH AM & FM

Currently not working. I have used this wonderful preamp for years! It's making loud drone noises instead of passing the signal through. There is OBVIOUS corrosion as shown in the photos. I have NOT TESTED any of the tubes. This will need significant bench time for repair, and cosmetic restoration. 

I used this for almost 20 years, without issue. It was placed on a very high shelf, so I didn't see the corrosion developing. I think it's well worth someone's time to get it looking and sounding as good as it's capable of. Tube preamps are rare, and this one does it all. 

The power cord is NOT Included. Sold "AS IS" "FINAL SALE".

Shipping is $50.00 insured to the lower 48 States. An Adult Signature is REQUIRED UPON DELIVERY with UPS.
