450TL

The 450TL is a 450 watt triode with a mu of 18 and is useable at full power to 40 MHz. It originated from the 450T "LO" varient. Early versions up through 1944, had hemispherical anode caps and a grid pin horizontally through the envelope like the 450T. The more common types had the grid exiting the envelope at an angle as in the second example from 1945.
