. AUG NMENT
/\ 5 (bnnect a low range output meter across speaker No. 66A7627R, is required for adyisniulg the tuner
voice coil and set volume control at maximum. For
greatest accuracy, keep output of receiver at ap-
proximately 1 watt (1 watt 1 1.79 volts on output
meter) throughout alignment by reducing signal gen-
erator output as stages are brought into alignment.
Use a small fibre screwdriver when aligning IF and
diode transformers. A special tool, Motorola Part
Cores. IMPORTANTZ |10 not push in on the align-
ment tool when adjusting the tuner cores; the -
slightest inward pressure may move tuner carriage
and result in inaccurate alignment. Remove recei-
ver top and bottom covers and thr- escutcheon and 1
dial scale assembly to expose all ad_]us-Lments.
