The 949H is a 500 watt triode with a mu of 19. Maximum usable frequency is 30 MHz. This tube is United's version of the 849H circa 1944. It is the same as the 849A but with a grid connection out the side for better high frequency operation. The 849A replaced the 849 with higher dissipation and filament current.
