1、GENERAL(B ELECTRIC Models P910AA, P911AA, P914AA, P945B, P950A, P960A, P995A, P996A (For Table 2, Component Substitution Chart, see page 39, at right) A check of battery condition and total current drain of the receiver should be made first. All current meas urements are made at quiescence with the

2、receiver turned bn, volume control at minimum, tuning gang closed, and with no-signalconditions. 2. Remove cabinet back by inserting a coin in the slot on the bottom of the set, giving it a slight twist. 3. Remove two 1/8 Phillips-head screws located un derneath the batteries. The total quiescent re

3、ceiver current drain is 12 to 20 mils. This is measured by inserting a milliammeter in series with the batteries. 4. Remove 1/8 Phillips-head screw located next to the tuning capacitor. 收音机爱 好者资料库 RadioFans.CN VOLUME R-25, MOST-OFTEN-NEEDED 1965 RADIO SERVICING INFORMATION GENERAL ELECTRIC Models P9
