I.F. Circuits: 456 KC

ALIGNMENT PROCEDURE
No attempt should be made to realign the various circuits until all other causes have been checked, unless the condition is so obvious as to indicate that realignment is necessary. Then proceed as follows: Volume Control full on. Low range A.C. meter connected across voice coil to indicate output. Keep signal generator attenuated so as to maintain 1/2 scale reading on output meter. Make certain that dial pointer is exactly on index line (top left side of dial plate) when variable condenser is fully meshed.
