Yes. The C-14A directional gyro can be used in place of the 332E-4 dir. gyro and 328A-3G slaving amp. However, the amplifier in the C-14A gyro is not enough to drive the compass card in the 331A-3G HSI. Therefore, the 341C-1 servo amplifier must be used in conjunction with the C-14A to function properly the Collins PN-101.
