🔍 Key Concepts

• Voltage gain in an audio amplifier • How tube characteristics (like transconductance) affect amplification • The role of external circuit components (plate load, transformers) in setting overall gain

💭 Think About

• Ask yourself: Does voltage gain depend only on the tube itself, or also on what is connected around the tube? • For a triode stage, how does changing the plate load resistor value affect the output signal size, if the tube stays the same? • If you add a step-up transformer at the output, what happens to the voltage seen by the next stage or by the load?

✅ Before You Answer

• Verify what tube transconductance (gm) physically represents (change in plate current for a change in grid voltage). • Consider how plate load impedance influences the voltage developed from a given change in plate current. • Think about whether a transformer step-up ratio can increase the voltage seen at its secondary, and whether that effectively changes the stage’s overall gain.
