For the most part, the KT-76C is a direct fit and form replacement for the KT-76A. However, there are considerations when replacing a KT-76A that was installed into a 28V aircraft installation. The original KT-76A utilized a voltage changeover (i.e. dropping resistor) kit for the KT-76A to be installed to a 28V installation. The KT-76C was designed to operate from any input voltage of 11-33 VDC. Therefore, the dropping resistor is not needed for the KT-76C in a 28V aircraft. The original droppiong resistor is removed from the original KT-76C wiring harness. In addition, the harness fuse needs to be changed from 3A to 5A. If an RFI suppression adapter was installed originally, then it must be removed as well.
The KT-78A is simply a low power version of the popular KT-76A transponder. The KT-78A peak power is 113 watts minimum while 200 watts for the KT-76A. The KT-78A was originally designed for low flying aircraft that operated in very local areas such as crop dusting (agriculture) applications. Both the KT-76A and KT-78A are 14 volt radios that utilize the same mounting rack and connector. Therefore, the higher power KT-76A is an ideal direct replacement for the KT-78A considering that the KT-78A has not been manufactured for many years and is therefore scarce on the used market.
Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 75% of the original exchange price. That is, it cannot cost SEA more than 75% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.

Although some manufacturers call out specific transponder antennas in their installation manuals, almost any transponder antenna can be used with any transponder. Various models are available based on the screw hole pattern desired and the speed & drag considerations based on the aircraft type.
Ultimately, it is the responsibility of the installer or installing agency to determine what antenna is suitable for the aircraft application.
