Red ge mastr channel guard tone network, 151.4 hz.
Here is a GE Mastr red Channel Guard Tone Element, part 19B205280G18, 151.4 Hz. These were used in the Shared Repeater Tone Panels, as well as late Mastr Pro, Early Exec II, etc. These are not the earlier heavy vibrating reeds, but the later plastic tone filters. Untested, but these rarely ever go bad.
