Serial Number: 6488. Power: 110-120V, 60 Hz, rated 105W. Country of Manufacture: Made in USA.

Output taps: 4 / 8 / 16 ohm speaker terminals. Includes: Amplifier unit only. CONDITION – Untested (Not Powered), Tubes Individually Verified. Tubes were pulled and bench-tested on a Sencore TC142 tube checker: 6L6 tests at 85% emission (GOOD range); 12AX7 tests at 100% emission (GOOD range) – this confirms the tubes themselves are healthy, but does NOT confirm the amplifier circuit, transformers, or capacitors function correctly. Top panel shows significant cosmetic damage: multiple names/initials scratched into the metal finish, plus general scuffing and scratching across the top surface – see photos closely, this is more than typical surface wear. Control knobs show grime/wear consistent with age; front panel lettering and chrome trim otherwise legible and intact. Not inspected for capacitor condition, cord integrity, or continuity beyond the tube bench tests described above. This is tube-era, mains-connected equipment that has not been powered on or serviced. Internal capacitors likely need replacement before use, and high voltages are present inside the chassis once powered. Strongly recommend a full inspection, cap job, and cord check by a qualified tech before first power-up – do not simply plug this in. Model: S-1000 II. Type: Integrated Tube Amplifier (mono).

Visual Condition: The chassis shows standard signs of 70-year-old age, including surface oxidation, dust, and patina. The front faceplate retains its classic Fisher aesthetic but may show wear. Please inspect the high-resolution photos for the exact tube complement and physical state of the transformers.
