Hi Joachim > 2. Pump up the +12V to handle the additional current. 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 ;) > Btw. if you would use something like the Meanwell T60B or the Taco TXL > 060-0522TI you could have +5V AND make the power supply cheaper. Then no > one would complain to pay more for the +5V supply. 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. Florian
