If isola tion transformer is not available, connect low side of signal generator to B- throug

2、h .1 mf capacitor. Connect low range output meter across speaker voice coil and set volume control at maximum. For greatest accuracy, keep output of receiver at ap proximately .05 watt (.05 watt .40 volt on out put meter) throughout alignment by reducing signal generator output as stages are brought
