This unit is an absolute dream project for a dedicated tube audio restoration expert or a valuable donor for rare, original Fisher components.

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. Pioneer of the Integrated Receiver: One of the most historically significant pieces of audio gear, marking the transition from separate components to the all-in-one receiver format. Massive Original Transformers: Built with heavy-duty iron that made Fisher the gold standard for mid-century American tube sound. Premier Restoration Candidate: For the audiophile who values the warm, musical “Fisher Sound, ” this is the ultimate platform for a complete rebuild. Model: 500 (Original Mono Series). Included: The Fisher 500 Chassis as shown in pictures. (Note: No external wood cabinet, speakers, or cables are included).
