hello bro, in this video I'm interested in discussing about voltage regulators for small currents that are commonly used to supply op-amps, tone controls, preamps and others.
I will discuss and versus 4 types of regulators in this video, namely : LM317-LM337 ICs voltage regulators, then L7812-L7912 regulators, then simple shunt resistor and zener regulator and the last voltage regulators that use transistors.
I made these four regulators into one pcb so they can be compared easily.
first I will measure the output voltage of each regulator and I will compare it using an oscilloscope how the ripple voltage is generated
second, I will compare each regulator in supplying the cmoy preamp and see the sweeptone results produced by the preamp using a different regulator
will there be a difference in the character of the sound produced by the cmoy preamp when using a different voltage regulator? check this video
