The Taylor tubes were American transmitting valves built for reliability. They were conservatively rated for a long life. This valve was designed for use up into the low VHF region at 60 MHz. The ratings given are for both CW and phone. For AM service as a class C amplifier the output was 38 Watts, for CW use the power rose to 44 Watts. The peak grid current was 25 mA fully driven. With an amplification factor of 20, a drive level of 3.6 W was specified for full output.
The classic envelope is 57 mm in diameter and, excluding the UX4 base pins, is 140 mm tall.
