Quad Rail or Double Differential Power Supply for Audio Amplifiers which require two differential voltages, one for the power stage and another one slightly higher, but at lower current for the preamplifier and drive stage. Can be used together with LME49810 or LM4702 based Audio Amplifier Power Stage, or any other amplifier which requires 4 rail supply, such as Class G or Class H Audio Amplifiers. The available Electrolytic Capacitors, have value in range of 4700uF to 22000uF each, and working voltage from 35V to 100V. For capacitors selection, please use the selection menu. If another value is needed than the listed ones, please contact us to check the availability.
