2A3
Summary:
The Stradi 2A3 tube is compatible with the original RCA 2A3, but it is made by improving the Eb tube, so the sound is closer to Eb.
It is a mono plate version and produces a higher output than the original RCA 2A3.
RCA developed the 2A3 tube as an output tube for audio.
It can produce suitable power output for home audio and has been widely known and used by the public. As it was a popular model, many American and European manufacturers, including the original 2A3 manufacturer RCA, produced 2A3 tubes a lot.
The Stradi 2A3 tube is compatible with the original RCA 2A3, but it is made by improving the Eb tube, so the sound is closer to Eb.
The Stradi 2A3 tube has been improved for greater output than RCA 2A3.
The RCA 2A3 tube has a maximum plate dissipation factor of 15 watt, but the Stradi 2A3 tube allows a maximum plate dissipation factor of 30 Watt, so it can produce higher output.
The reason why the Stradi 2A3 tube was developed based on the Eb tube is to make it a Mono Plate version that many people prefer.
The Eb model can support up to 30 Watts which is suitable to increase the Stradi 2A3 tube's maximum plate dissipation.
Besides, for better sound quality, several improvements were applied.
In particular, to reduce the distortion that inevitably occurs during amplification, we use our own Ladder-Type FrameGrid and Minimization of Filament End-Loss structure.
By applying these improvements, clearer sound and wide frequency characteristics were achieved.
Available in matched pairs, quad sets, and singles.
