2、NFORMATION EMERSON Chassis 120836, Models 32P09, 32P10, 32P11 CHASSIS 120836 CONDITIONS FOR VOLTAGE MEASUREMENTS CAUTION DO NOT OPERATE CHASSIS WITHOUT DUMMY LOAD ATTACHED SINCE THIS MAY RESULT IN DAMAGE TO THE AUDIO OUTPUT TRANSISTORS Voltage readings shown an the schematic diogram are positive DC,

3、 measured using a VTVM between the points indicated and chassis ground. All measurements were made with controls set fully counter clockwise, and line valtage maintained at 120 valts, 60 cps AC. Allow 10% variation in readings obtained ta compensate for normal component tolerances.
