Linear Power Supply

Post by JohnG » Tue Jan 30, 2018 8:11 pm

I am toying with the idea of having a linear power supply produced to use as a exchangeable power supply for a few different components.
At present I have two Solid State Phonostages. I will add a DAC and a Computer throughout the coming year.
As I progress through the various models and upgrades over the coming years of the named components, there seems to me to be a benefit in having a Power Supply that will allow each component to perform at its best.
Is there a one type Linear Power Supply Design that will suit multi components or will the devices require a individual matched supply.

You need to work out what different voltage and current each one needs.
Resistance isn't futile it's V / I.

I can't answer the power requirements of each device at present. I know my original Phonostages schematic is 15v and the Clones Paperwork shows a Power Output of 5W.
Is there a loss of performance if a variable voltage design is to be used ?

It depends, but normally there is a range you can cover below that you need to look at a different transformer. It depends. A bench linear for example will cover as much a range as you need.
