It all begun when i was 12 yo, age when most youngsters go and play soccer, well i was playing with soldering iron and built a totally useless yet cool electronic circuit to convert light to sound. So no wonder that after all this time i still know how to put together a couple of resistors and capacitors and my power supply for MCE 5 mic to Minidisc is done, at least in that prototype i just had confirmation that the schematics make sense and the wiring is as expected.

I could not get there without the help of this guy, a real sound expert and of the support people at Beyerdynamic. More detail in the tech section when the full circuit is in place.
