Discussion
Match each adjustment with the part of the band it affects most.
List I
A. Padder capacitor
B. Trimmer capacitor
C. IF transformer core
List II
P. Low-frequency end
Q. High-frequency end
R. All frequencies equally
Select the correct match.
Answer: C
The correct pairing is A-P, B-Q, C-R. A series padder dominates where the tuning capacitance is largest, a parallel trimmer where it is smallest, and the intermediate frequency transformer works at a fixed frequency so its alignment affects every station equally. Knowing which adjustment acts where is what turns an alignment from guesswork into a short, ordered procedure.
