Diode - D606a, b - |S20ZS code number 4822130 31026 is changed into tS2076A codenumber 53ZZ 1gA g47g2. Resistor R638a, b and R63ga, b - 1 kOtr (circuit diagram) are safety resistors, code number 4822 111 30602 Resistor R405a, b - 10 kOtr is changed into 20 kOB. Between base and collector of TSg01 a capacitor of 1 nF AAj is added. Allgnment procedure quiescent current For adjusting the quiescent current, the voltage across R634a, b is measured, and adjusted by R6g2a, b at a value of 12 mV t 2 mV. The zero volts adjustment is to be done with R6g1a, b instead of R692a, b. For the alignment of the power indicators, the input- signal level must be adjusted for 20 V rms output at 1 kHz with no load. How adjust R491a, b for 0 dB reading on the power indicator.
