Power supply module

[Jrp27]

Wondering if anyone has used lm317 based variable power supply for their amps?

Is it a good idea to use of the shelf power supply modules instead of the regular tranny+ caps combo?

Something like this-

Imported AC/DC 3-40V LM317 Adjustable Voltage Regulator Step-down Power Supply Module: Amazon.in: Industrial & Scientific

First question: What kind of amp are we talking about here?

Hi,

No. It is a very bad idea. They generally cannot provide
remotely enough output current for audio power amplifiers.

rgds, sreten.

Regulated supplies are generally simply not needed.

This module can deliver 40v at 2 amps.

Will this module be able to power a 150 watt amp, say like the esp p101 amp

No it can't.

Nope, even if that power supply could deliver "40v at 2 amps", that's only 80 watts.

no hope.
Forget about regulating power for Power Amplifiers until AFTER you learn how Power Amplifiers work.
