The screen volts control is not a rotary potentiometer, it's a multiple position switch. The anode and screen voltages measured on the valve sockets will not match those selected on the switches. This is because the CT160 works using AC voltages. You are advised to consult the service manual.
Measured AC voltage should be 1.1 x selected voltage -2 +6%.
