¡Hecho!
Disculpa la tardanza, Popopo.
Te he enviado un correo con el justificante y mis datos postales.
Gracias y un saludo.

Añado información importante de la WEB oficial:
Sinclair Spectrum Composite Mod PCB
I designed a PCB to house several versions of the Spectrum Composite Mod. Details of how to implement the PCB can be found in my series on Refurbishing a 48K Rubber Keyed Spectrum on my companion site, Projectavr.com. The PCB simply replaces the existing Modulator PCB. I would recommend that you remove the original carefully and put it in storage, in case you ever wish to re-install it for authenticity.
The PCB itself is very simple, requiring just a few components to operate. Choose which of the three options you would like to use.
Option 1 is an Inverted Emitter Follower recommended to me by Andrew Gostling in an attempt to get a Dell UltraSharp 2007FP Monitor to work with a 48K Spectrum. Sadly, the monitor is extremely picky about it’s composite input and is well documented for it. In this instance it didn’t work. However, the composite mod works with all the other monitors I have tried it with.
Option 2 is a simple NPN transistor and resistor mod. the NPN Transistor can be any general purpose device. I have used a BC547 in the past.
Option 3 is a single 100uF capacitor which is seen to be the minimum required.
I have had several conversations around the need for other components with regard to the composite mod. Some say that it is not necessary at all and others say that, in case the monitor goes faulty or is very badly designed, it can feed voltage back to the Spectrum. I recommend you do your own research and choose the option that best suits you (including a direct connection and/or suspending the components outside of the modulator box retaining the original PCB inside the modulator).
