Very rare Model 500 and 600t sold as a set. Beautiful statement pieces from Kenwood. The only issues with the these are as follows: The 600t Tuner has a stuck signal meter. The Model 500’s volume control is a bit scratchy. Both units have etched numbers - the 500 is exterior and shown in the photos, and the 600t has the same etching, but on the interior siding. Both units function perfectly, otherwise. The amp sounds incredible, and the tuner is one of the finest ever built. These will securely packaged and shipped in two separate boxes. Shipping charges shown are therefore to be doubled. Guaranteed to arrive as pictured and described. Due to the nature of vintage electronics, no warranty is stated or implied, and no returns accepted. Please ask any questions beforehand. Please view all photos and video.
