RCA 6AU6A Vacuum Tubes
The 6AU6A and 6AU6 are pentode amplifiers having a sharp cutoff control characteristic. With high transconductance and low grid to plate capacitance they are intended for service as either RF or AF amplfiers. In addition, thermal characteristic of the heater of the 6AU6A are controlled such that heater voltage surges during the warm-up cycle are minimized provided it is ised with other types which are similarly controlled.
Except for the controlled heater warm-up time and higher heater-cathode voltage rating of the 6AU6A, the two tubes are identical.
