Perfect for collectors or those who appreciate the aesthetics of classic radios, this Zenith model is a true gem. Zenith quality model k721 with 7 tested vacuum tubes. Long distance reception receiver. Has been serviced, tested, inspected and cleaned as needed. Ran unit for 6 hours after servicing and fine tuning and no issues found. Spent close to 6 hours on servicing, fine tuning, adjustments and cleaning/testing. Power supply cord was replaced as well as several tubes. The sound is pristine and mind blowing and loud.
