Figure 0.15 (a) Triode resistance coupled amplifier. The hot input terminal goes to the grid of the triode. The cold input terminal is grounded. There is a resistor, Rc, from the grid to ground. The cathode goes to ground through the parallel combination of Rk and Ck. The plate goes through a resistor Rb to B plus. The plate also goes through a capacitor Cb to a resistor Rcf. This is the grid resistor of the following stage.

Figure 0.15 (b) Pentode Resistance Coupled Amplifier. The hot input terminal goes to the grid of the pentode. The cold input terminal is grounded. There is a resistor, Rc, from the grid to ground. The cathode goes to ground through the parallel combination of Rk and Ck. The screen grid, grid number 2, goes through a resistor, Rc2 to B plus. The screen grid also goes through a capacitor Cc2 to ground. The suppressor grid, grid 3 is connected to the cathode. The plate goes through a resistor Rb to B plus. The plate also goes through a capacitor Cb to a resistor Rcf. This is the grid resistor of the following stage. This completes the verbal description.
