Switch the power on with no input and no load applied to the unit. 4. Adjust VRI to obtain a reading of 22mV ±lOmV between TPI (+) and TP2 (-). 5. Repeat the above operation for other channel assemblies. 6. Readjust after aging for at least 10 minutes. Reference: Center DC out put voltage tolerance: OV ± 100mV. Equalizer Amplifier Adjustment 1. Short circuit the PHONO terminals. 2. Adjust VRI to reduce the TPI voltage to at least ±l OOmV. 3. Also adjust VR2 to reduce th e TP2 volta ge to at least ±lOOmV.
