ASM-1 and other questions

Several companies in the UK have tried building and selling "audio standard" power supplies.
The only problem is that by the time that you have packaged them properly and safely the 
cost is to high for diy applications.

You could use a "wall wart" to supply a reasonable ac or "dc" supply to your project and then 
add a good regulator within the box.

A good power supply is really very important (you wouldn't believe the number of pro-audio 
toys that are compromised by thier PSU's).  Aim for a low output impeadance (the line doesn't 
dip if you draw more current) good regulation (this is really important if the supply is used as a 
reference anywhere eg the exponential converter reference current or even the front panel 
pitch pots!) and last but not least make sure that your grounding system is good.
