Removed from Wilcox transmitters, these 350 watt modulation transformers are ready for a second life. They operated plate to plate on a pair of class B, 813 valves to modulate a single 250TL RF amp. This is an auto-transformer with multiple series windings. Call for details. 5-1/4" x 6-1/4" x 7-1/2" high, including insulators. We will include a copy of the Wilcox circuit in which the transformer was used.
