36VDC will cause some increased internal heating, but above 36VDC may cause
IC failure.
OPERATING POINTS
An internal reference voltage equal to 1/2 the supply voltage is generated. All
audio stage IC inputs and outputs should show a DC level equal to this voltage
when measured with a high impedance meter. Audio inputs and outputs are
capacitor coupled and ground referenced.
MODIFICATIONS
ADDITIONAL GAIN
If more gain is required for a particular application increase the values of R25
(left) and R34 (right). 20K ohms adds 6dB, 30K ohms adds 10dB, 62K adds
16dB, 100K adds 20dB. A corresponding decrease in the input clipping level will
result.
