Unique Homemade ONAN Frequency Meter with Triplet A.C. Voltmeter & Heating Coils - Farm Use

This is a one-of-a-kind vintage ONAN frequency meter unit, possibly homemade, featuring three large heating coils, a JBI Model 34-F frequency meter, and a Triplet A.C. Voltmeter. Each coil outlet is equipped with an individual switch, indicating it may have been custom-built for specific applications on a farm, possibly for providing heat to farm animals like chickens or for another agricultural purpose.

•Homemade Design: Custom-built with individual switches for each coil, suggesting specific control of heat distribution.

•Frequency Meter: JBI Model 34-F, measures 56-64 cycles per second (Hz).

•A.C. Voltage Meter: Triplet A.C. Voltmeter, measures 0-150 volts.

•Heating Coils: Three large resistive coils with protective wire cage, heat up when powered on, possibly used for providing heat to farm animals or agricultural equipment.

•Farm Origin: This device came from a farm, which supports the idea that it was built for agricultural purposes.

•Application: Likely used for farm heating, backup power, or testing systems, possibly for animal care (e.g., chickens or other livestock needing warmth).

•Condition: Tested and working. The heating coils activate when plugged in, and both the frequency meter and voltmeter are functional.

This unique, homemade piece would be a fascinating addition to any collection of vintage industrial or farm equipment. Given its custom design and farm history, it is truly a one-of-a-kind find, with nothing else like it available.
