SMPS in guitar amps

[guitarzan]

Hi Guys

Switch-Mode Power Supplies (SMPS) are used in almost every piece of consumer electronics today (2018) and a few guitar and bass amps use them, too. There are some special considerations when incorporating SMPS into audio products and we will explore some of these and their solutions in this area.

Have fun

In reality, Class D amps are sort of a ripple filtered SMPS.... lot of those being used these days...good ones...bad ones... Regarding SMPS, many say that the PS isn't in the audio signal chain.... but I disagree.... it is inherent in the chain.  Use a poorly designed PS (or a noisy SMPS) and you have a lousy amp.
