[sdiy] power supply

[charles kerr]

hello everyone, 
a question and topic change, how do all you synth diyers power your trial circuits? is it best to try out on breadboard with a battery power supply? I was thinking of (I have a Doepfer case with +12v, -12v, 0v and +5v) putting the power out to a blank faceplate and then jacking out of sockets to crocodile clips onto a breadboard/proto circuit but I got to thinking that if I make any mistakes in the circuit than I could mash up my whole synth power supply, would it be alright if I inserted a fuse? but what rating etc? With batteries the supply would not be very constant would it, the supply would drop gradually and over the time that I am trying things out I would be spending an awful lot on batteries, something I would like to avoid if possible.
I have noticed that a lot of synth diy stuff is on a 15v power supply so I was considering buying a Blacet supply and using this as a main source for a modular - but for the same reason as above I would prefer to keep this for finished modules. i think what I need is a small 15v supply with enough ampage for one module, where can I get one from? all bench supplies I see are +15v but don't have -15v (same with 12v) could anyone reccomend a solution?
 
no doubt anyone who has read this far is thinking "duur - what a twit!" but if you could help me out I would be eternally grateful
 
thanks for reading and thanks in advance for any response
charlie
