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. |
