Attached is a photo of the pitot heater thermostat that was attached to the pitot (pn: 1500118-4) of my 1978 T337H. It no longer works and one of the ears for the power connection has broken off. Cessna lists only the combination pitot, thermostat and heater assembly. Does any one know where to source the thermostat unit only. It has the name stemco on it . A search for the stemco company has uncovered that they are out of business.
It is 5/8 inches in diameter. The aircraft has a 28 volt system.
Any help is greatly appreciated.
