🔍 Key Concepts

• RF amplifier interstage coupling methods (link, capacitive, transformer) • How link coupling affects isolation between stages and tank circuit tuning • Effects of tube (valve) interelectrode capacitance on tuned L/C circuits

💭 Think About

• Think about the physical nature of link coupling: what is actually connected to what, and what is only magnetically coupled? • How does magnetic (inductive) coupling change the way tube capacitances influence the tuned circuit compared with direct or capacitive coupling? • Would using a loosely coupled link generally make layout and mechanical construction more or less flexible?

✅ Before You Answer

• Identify whether link coupling physically separates the tank coil from the tube elements or connects them directly. • Consider if isolating the tuned circuit from the tube’s interelectrode capacitances would tend to reduce their effect on the tank’s L/C ratio. • Decide independently whether statement A is true, and then whether statement B is true; only then evaluate C (both) or D (neither).
