120-0308-00/Repairs

Bill Schell sold rewound 120-308's in the late 2000s. Chuck Harris rewound them in the 2010s. Both products were machine-wound in the "universal" pattern, like the Tek originals. It's also possible to rewind one yourself, if you build a simple winder and use the "layer wind with retrace" pattern. This has been discussed at www.antiqueradios.com, and the TekScopes and TekScopes2 groups at groups.io . I successfully rewound a similar transformer, 120-0360-00 for the Type 453 scope, and documented the recipe at groups.io. Vintage dave, 5 May 2026
