The 6146 is the last tube that I tested. It is a power tube with 3 screens, making it another pentode. The main applications for the 6146 are as an amplifier or an oscillator. It has a typical heater voltage of 6.3 volts. (RCA)
|This is a diagram of the 6146 tube.|
With a 65.9 volt bias and a 275 volt potential across the screen, this tube produced a secondary emission curve with the plate potential ranging up to 200 volts. The current starts to drop when the plate potential reaches about 25 volts, and continues to drop until the plate potential reaches about 150 volts.
