[QUOTE="JimGore, post: 715626, member: 3"] It's common practice to regulate the small signal stage (IPS and VAS) section of an amplifier because it's easy to do (the small signal stage consumes very little current). Normally the output stage which consumes the heavy current is left unregulated. [b]I can build the voltage regulation for the small signal stage directly onto the PCB, but I am wondering whether I should?[/b] - If I do, then you will be *stuck* using my idea of regulation, though there is 1 less PCB you need to worry about. - If I don't you can use whatever you like best, but it involves an additional PCB and more wiring, etc. Opinions? Kind regards, Ian. [/QUOTE]
