  Condition: For Parts or Not Working
  This Polarad TSA-W Spectrum Analyzer system — comprising the STU-2 BW RF Tuning Unit and DU-2 Display Unit — is being sold as-is for parts or repair. We were unable to fully test this system at our facility, so no functionality is guaranteed. The unit is in vintage used condition with paint wear and chips on the cabinet exterior (visible on the rear and lower panels), though the front panels and controls appear intact and the CRT screen shows no obvious damage. Internal components are accessible and visible — the chassis opens to reveal a large cylindrical cavity/waveguide assembly and internal wiring. Two 6.25A fuses are present at the rear power input. This system requires freight shipping due to its size and weight (~133 lbs). Please review all photos carefully and contact us with any questions before purchasing.
