RE: Linear PSU again: help needed




Hi guys,
Today, just hours ago i made huge step forward in my cMP set up.
Ones again -power supply ! I use low profile computer case and have not enough
space for everething i want to put in , so in time my MoBo died, i change design. Cut off some bottom part of a case to provide access to back side of MoBo.
First, i follow JackWrong way , but just install small electrolit cap on open part of MoBo and move some of my caps on back of moBo . It was posible use short wire 30-35 mm longfor big caps.
Difficalt to say about improvment , becouse I start to use Buffalo DAC and tube Buffer, belived it was also on part of cMP.
Access to back of Mobo ,give me ability to mesure by my basic PC Oscilloscope what
i got . I find difference 2-3 fold in mvolt on deferent end of 35mm wire.
So , using strip of PCB board as a wire (should be square size or so, but not narrow)
I connect my caps to Mobo.
Result- excellent. Sound more clean, bass more controlled,mach better resolution on low level. I still not mesured what I got by Oscilloscope, planned make same approch
for CPU +12volt and added small NOS cap all around, will see what happen.
Gene.
