Safety

Tube chassis: lethal B+ voltages remain after switch-off — discharge before service. Never power up an unrestored unit on original electrolytics. Serial tag is an ink stamp on a plastic label (often missing/faded); the value depends on original transformers (replaced/rewound iron cuts price sharply).

What moves the price

Sold-price aggregates are not collected yet, so the archive gives no figure — condition, originality of the transformers and a documented recap move this model more than any list price.
