Hola
Lamento no poder ayudarte con los comercios de España ya que soy de Argentina.
Yo preguntaría en casas de electronica y de equipamiento pro; y el ebay español.
Como para darte una idea de lo que yo encuentro aquí.
Algunos son fuente y pre a la vez. Y salvo el 2do en los demás tendría que hacer algun destripe.

Mi consejo:mucho más barato es pedir aprobación del personal experto de este foro y quizá tambien de che.es sobre el siguiente circuito del documento citado.
Phantom powering electret microphone from phantom power
Simplest circuit
This circuit is a very simple method of connecting an electret microphone capsule to the a balanced phantom powered (48V) mixer XLR input.

Note that this is a very simple "hack" to interface an electret microphone capsule to a mixer. This circuit works but has it's downsides like sensitivity to noise in phantom power, unblanced signal transmission (prone to interference) and high output impedance (can't properly drive long cables). This circuit can be used to test electret capsules connected to mixer using very short cable. This circuit makes very high level popping noise when it is connected/disconnected from the mixer or when the phantom power is turned or disconnected. Other downside is that this circuit loads the phantom power in very unbalanced way which can disturb some older mixers (in some mixers input transformer can saturate if such exists, in that case try adding 47 ohom resistor between pins 1 and 3).
In practice this circuit seems at least to work on modern mixers, but I don't recommend this circuit for any real recording or PA application For any real use you are much happier with a better quality balanced circuit. They are more complicated but perform much better.

Una papa. Con una hembra miniplug, cable, resistencia y macho XLR ya está.
No recuerdo Xavi si tu soldabas o no. En el caso de que no, los componentes que lleva se podrían unir bastante bien mecánicamente.
