🔍 Key Concepts

• Shunt-fed plate circuit operation in a vacuum tube RF amplifier • What an RF choke (plate RFC) does for RF vs. DC in the plate circuit • Effects of an RF choke short circuit on DC path, RF path, and the tank circuit

💭 Think About

• Think about what the RF choke normally blocks and what it normally passes. If it becomes a short, how does that change the paths for RF and DC? • Consider what the plate tank circuit is connected to. If the choke is shorted, what does the tank "see" at the supply side? • How would plate current and RF output be affected if RF energy is no longer isolated from the power supply by the choke?

✅ Before You Answer

• Trace the DC plate current path with a good choke vs. a shorted choke • Trace the RF path from the tube plate through the tank and see what happens when the supply side becomes a low‑impedance point • Ask: if the choke is shorted, is there any condition under which RF output could still be normal, or are multiple things likely to go wrong at once?

Question 1 of 20

A shunt-fed plate circuit of a vacuum tube amplifier has a short circuit of the plate RF choke. What happens?

The plate tank circuit would be effectively shorted

The DC plate current would increase, possibly to excess

No RF output could be expected

All of the above
