VT-73 Motorola Sound IN video?

Unfortunately you wont be able to align this set with a B&K 415. The 415 is for the more modern 44 MHz IF, while the VT-71 uses the older 21 MHz IF.

Are you referring to the coil in the canister with the 1N34 detector diode ? It corresponds to A4 in the Sams alignment info. It affects the video IF curve along with A5 and A6. You'll need a sweep generator with markers and scope to properly adjust those coils.

I use a Wavetek 1002 for my alignments.
