The NTE7147 is a power amplifier in a 9鈥揕ead SIP type package designed for use in 90 degree color
vertical deflection systems for frame frequencies of 50Hz to 160Hz. This device provides a high
CMRR current driven differential input. Due to the bridge configuration of the two output stages, DC鈥?/div>
coupling of the deflection coil is achieved.
