PSU for many amp blocks

[Specterx]

Hello,

I'm planning to build 3 stereo amp blocks(GC). Is it possible to connect them to PSU like in the image attached here? Is this connection type noisy for Amp?

Hello,

I have planned to build three stereo amp. blocks and to use power supply with one output(+ and -). Is it possible to connect PSU to amps like in the picture attached? is it noisy connection? is there another sollution?

With best regards,

but is it good that 3 amp blocks share one power source from PSU? Is there any sollution better than parallel connection?

 

[G4ME]

sure, 3 different PSU

 

[Specterx]

Does anybody have schematic of PSU where are 3 independent outputs and one torodial type transformer on input?

 

[autoexec]

do you mean putting 3 bridge rectifiers in parrallel?

 

[Specterx]

yes, but only in case they are powered from one PSU. Can I use torodial tansformer for many Power Block units?

Yes, you can. The inputs to the diode bridges are in parallel and each bridge feeds its own capacitors and amp.
