The SE-300B has been designed and manufactured under the premise of obtaining the highest quality and performance without any type of conditioning. With a refined construction and optimal components, it manages to obtain a defined and faithful sound, and an impeccable response. In essence it is a Single-Ended amplifier, pure class A, what makes it stand out is its refined design as well as the use of unbeatable components and manufacturing techniques at each stage.  

Details such as a power supply for the tubes, both high voltage and filament, fully stabilized and filtered with a separate and shielded power supply, PIO by-pass capacitors, gold-plated sockets, top-quality input-output connectors or power transformers. In-house designed and manufactured output, with grain oriented sheet metal and multiple interleaved windings, encapsulated in steel shielding, make this amplifier close to perfection.

The SE-300B is totally versatile, on the one hand the almost 9 W RMS provide enough power for low and medium output loudspeakers, while on the other hand the non-existent output noise values make it ideal for working with high output loudspeakers , all this together with the fact that the equipment has an output impedance selector for 4, 6 and 8 Ohms (other impedances on request).
