The Stradi Ed reproduces Valvo's Ed in a modern way.
The Ed tube is considered as the industrial version of the AD1.
The Ed tube’s BASE is Post 7 Pin(P7), which, as its name suggests, was mainly used in the telecommunication field. However, when used for audio, the sound was very good, so it tends to be the best among European direct-heated triodes.
The Stradi Ed reproduces Valvo's Ed in a modern way, but the company's unique microphonic reduction and filament end-loss reduction structures are applied.
To minimize microphonic and distortion, which can be a problem in sound reproduction in audio, we apply a Ladder-Type FrameGrid. It makes the sounds clearer and better so that you can fully enjoy your music.
Available in matched pairs, quad sets, and singles.
