Greetings to all, I am looking for the external;l heating elements for the RF amp meters in the TMC TAC-1 tuner. To keep the purists at bay, let me say that I use this tuner to match my KW-1 to a balanced line. 73 de Lon W. Cottingham, K5JV 1110 Golden Bear Ln. Kingwood, TX 77339 281-358-4207 281-433-7532 Cell
