🔍 Key Concepts

• Function of a coupling transformer between audio stages • What happens when a secondary winding is open (no continuity) • How impedance (RC) coupling with a grid resistor and coupling capacitor works compared to transformer coupling

💭 Think About

• If the secondary winding is open, what immediate effect does that have on the signal path to the first AF stage? • Is it always necessary to replace a faulty transformer to restore signal, or can you reconfigure the circuit to pass audio another way? • Which option(s) would actually restore coupling between stages with parts typically available on board?

✅ Before You Answer

• Verify which choice(s) would restore an AC signal path from the previous stage to the grid of the first AF tube/transistor • Check whether transformer replacement is the ONLY practical repair mentioned, or if a reconfiguration to RC (impedance) coupling is also a valid standard approach • Make sure the selected option(s) would be considered a satisfactory repair in an exam context, not just a theoretical possibility
