🔍 Key Concepts

• Class A amplifier operating point (biasing) and how it affects linearity • Effects of supply voltages (plate/screen) and coupling capacitors on signal shape • Relationship between signal amplitude and load impedance and distortion

💭 Think About

• For each option, ask yourself: Would this condition push the tube out of its linear region during part of the signal cycle? • Think about how a leaky or shorted coupling capacitor changes the DC bias on the next stage—does that tend to increase or decrease distortion? • Consider whether incorrect load impedance and excessive signal amplitude can clip the waveform even if the tube itself is good.

✅ Before You Answer

• For each choice (A, B, C), decide if it is a plausible cause of non‑linear operation in a Class A tube amplifier • Mentally sketch what happens to the plate current vs. grid voltage curve when bias or supply voltages are wrong • Before choosing, verify whether any one of A, B, or C could NOT cause distortion; if they all could, what does that imply about option D?
