of manual controls, control voltage inputs and audio inputs
For A-124 it's R1 (27k) located just behind the potentiometer for audio
level control. If you reduce the value (factory 27k) of this resistor the
max. loudness increases. Another solution will be the usage of the planned
A-183-3 amplifier module.
