What is a Coupling Capacitor?
Coupling capacitors are useful in many types of circuits where AC signals are the desired signals to be output while DC signals are just used for providing power to certain components in the circuit but should not appear in the output.

Yes, reducing the coupling capacitor will reduce the bass-response. Technically, the capacitor and the output impedance of the tube-stage forms a simple high-pass filter. Your circuit is very typical: You have the 100k plate resistor. Along with the internal resistance of the triode, that roughly gives an output impedance of 50k Ohm.
How to find coupling and decoupling capacitor values?
In the case of (AC) coupling capacitors you want the most optimum capacitor for your signal frequencies. In practice the actual value of the capacitor does not matter too much as long as it is "enough". For example, to suppress a supply ripple of 100 Hz, a 10 nF capacitor isn''t going to help much. A 100 uF capacitor will help but so will a 47

What is the value of a coupling capacitor?
The value of the coupling capacitor depends on the frequency of the AC signal being passed through. Capacitors are reactive devices, meaning they offer different impedance (or resistance) to signals of different frequencies. To low-frequency signals, such as DC with a frequency of 0Hz, capacitors offer very high resistance.
What are coupling capacitors used for?
For example, in a circuit that includes audio signal processing and DC bias, coupling capacitors can ensure that the AC signal of audio is smoothly transmitted between various circuit modules without being interfered with by the DC bias voltage, thereby ensuring the purity of the audio signal and the normal realization of the circuit function.
What is the difference between DC power and coupling capacitor?
For example, a coupling capacitor normally is used in an audio circuits, such as a microphone circuit. DC power is used to give power to parts of the circuit, such as the microphone, which needs DC power to operate. So DC signals must be present in the circuit for powering purposes.
What is the difference between a coupling capacitor and a decoupling capacitor?
While coupling capacitors pass through AC signals to output, do pretty much the opposite; decoupling capacitors shunt AC signals to ground and passes through the DC signal in a circuit. Decoupling capacitors are designed to purify DC signals of AC noise.
