Hi all
Im new here and a complete novice regarding electronic design but I am interested in learning so I can build my own amp. I like the idea of a pure class A running off a separate power supply
Can anyone here tell me what the advantages and disadvantages are of having an outboard power supply? Apart from cost, my understanding it that if the transformers are kept at a distance it dramatically improves interference?
If running long cables to carry a dc voltage to the amps what are the problems likely incurred? Im thinking rf interference unless screened? I know the likes of naim claim outboard power is the only way for hi end sound.
Any advice and opinions greatly appreciated
Cheers🙂

I use an HP 6253A and 6228B Dual DC Power Supply. I like the HP 6228B Dual DC Power Supply with voltage tracking mode, where both supplies can be adjusted with one knob. Several models are on eBay for under $100. Best of all they have current limit down to zero. This means you can bring up a newly built amp without damage.
