Voltage and resistance at V4 - 1 may vary more than 20%. Voltage and resistance depend on ALC ZERO (R30) setting and R38 value. Resistance is 81 to 96 W ( 20%) if R38 is 68 W. Resistance is 73 to92 W ( 20%) if R38 is not installed. Refer to =12=> in illustration section.

Resistance at V4 - 6 depends on polarity of ohmmeter. Larger resistance is with positive lead of the ohmmeter connected to ground.

Resistance at V4 - 7 is 3 KW ( 20%) if R46 is 3300 W, Refer to =9=> in illustration section.

Voltage at V4 - 8 is 275/170 Vdc ( 20%) and resistance is 21 KW ( 20%) if R202 is not in V4B plate circuit. Refer to =9=> in illustration section.

Voltage at V5 - 1 and V5 - 6 is 275/250 Vdc ( 20%) and resistance is 9 KW ( 20%) if L3 is in plate circuit instead of R197.Refer to =16=> in illustration section.

Voltage at V5 - 2 and V5 - 7 is- 64/-0.05 Vdc ( 20%) and resistance is 480 KW ( 20%) if R212 has not been added. Refer to =14=> in illustration section.

Voltage at V5 - 3 and V5 - 8 may vary more than 20%. Voltage and resistance depend on 1st MIX BAL (R24) setting.

Resistance at V6 - 1 and V6 - 6 depends on polarity of ohmmeter. and values of R143 and R18 used. Larger resistance is with positive lead of the ohmmeter connected to ground. Resistance is 28 KW or KW ( 20%) if R18 is 47 KW. Resistance is 24 KW or 11 KW ( 20%) if R143 is 1500 W . Resistance is 27 0r 11.5 KW ( 20%) if R18 is 47KW and R143 is W Refer to =22=> and =12=> in illustration section.

Voltage at V8 - 3 is -0.4/145 Vdc ( 20%) and resistance is 30 KW ( 20%) if R105 is 22 KW.Refer to =31=> in illustration section.

Resistance at V9 - 3 and V10 - 3 depends polarity of ohmmeter. smaller resistance is with positive lead of the ohmmeter connected to ground.

Resistance and voltage at V12 - 7 depend on position of OFF-ON- NB-CAL switch and the polarity of the ohmmeter. The voltage and resistance are normally checked with OFF-ON- NB-CAL switch in the ON position. The smaller resistance is with the positive lead of the ohmmeter connected to ground. (Because of very high resistance of R11, reversal of ohmmeter leads may not make a noticeable change in readings.) AC Voltage is measured with the OFF-ON- NB-CAL switch in the CAL position. Resistance to ground in the CAL position is 1000 W ( 20%).

Voltage at V13 - 3 is 195/180 Vdc ( 20%) an resistance is 51 KW ( 20%) if R125 is 47 KW. Refer to =27-11=> in illustration section.

Voltage at V14 - 1 may vary more than 20%. Voltage depends on VOX TIME CONSTANT (R43) setting, ANTI VOX GAIN (R45) setting, and wether or not R199 has been added. Refer to =8=> in illustration section.

Voltage at V14 - 2 may vary more than 20%. Voltage and resistanc depends on ANTI VOX GAIN (R45) SETTING.

Voltage at V14 - 3 may vary more than 20%. Voltage depends on VOX TIME CONSTANT (R43) setting and wheter or not R199 has been added. Refer to =8=> in illustration section.

Voltage at V14 - 6 may vary more than 20%. Voltage depends on VOX TIME CONSTANT (R43) setting and wheter or not R199 has been added. Refer to =8=> in illustration section.

Voltage at V14 - 7 may vary more than 20%. Voltage depends on VOX GAIN (R39) settingand wheter or not R201 has been added. Refer to =7=> in illustration section.

Voltage and resistance at V14 - 8 may vary more than 20%.Voltage depends on VOX GAIN (R39) setting and wheter or not R201 has been added.If R201 has not been added, resistance is 0 to 250 KW ( 20%); with no VOX input, voltagre at V14 - 8 is 0 Vdc, Refer to =7=> in illustration section.

Voltage at V14 - 9 may vary more than 20%. Voltage depends on VOX GAIN (R39) settingand wheter or not R201 has been added.Refer to =7=> in illustration section.

Voltage at V16 - 1 is 3.0/2.8 Vdc (20%) and resistance is 5600 W ( 20%) if V16 - 1 is connected to V15 - 2. Refer to =26=> in illustration section.
