Re: [Doepfer_a100] Request for a +5V/+12V/-12V power supply in the standard housings

It does not matter whether the 5V supply eats from the total power via a 
separate rail or from the +12V rail. 2nd main sentence of 
thermodynamcis: "the sum of all energy in a systems stays always the 
same". You may be able to change capitalism or the catholic church or 
the behaviour of a small synth producer - but you cannot change the laws 
of nature ;)

The usage of switching power supplies was often discussed in this group. 
Final result: it cannot be recommended. For more details please consult 
the web-archive of the mail list.
