Ho più di qualche perplessità sui claim... 
ma potrebbe essere divertente provarlo.

Fonte: “Diy Electronics & Engineering” (sul faccialibro).While many believe you require costly vacuum tubes to achieve the analog audio quality of warm sounds, an optocoupler plus some other common components are able to create your own unique experience.
The TLP621 and BC547 work together to modulate the incoming audio signal, producing even harmonic distortion characteristics that resemble traditional tube amplification systems resulting in a warming effect through; harmonic structure enhancement to original audio content.
This particular circuit design makes this an ideal candidate for audiophile constructors wanting to build their own DIY projects as well as constructors building guitar effects devices and creating sounds via a digital processor.
In fact, while the circuit looks simple when first implemented the actual theory of operation behind this circuit is quite complex and highly sophisticated!
