Using a push-pull 2A3 output stage, it combines tonal richness with greater drive capability than many traditional triode designs.\u003c\/p\u003e\n\u003cp\u003eKey features:\u003c\/p\u003e\n\u003cp\u003e• integrated valve amplifier\u003cbr\u003e• 2A3 directly heated triode output stage\u003cbr\u003e• push-pull Class A design\u003cbr\u003e• 18W per channel output\u003cbr\u003e• 3 x line inputs\u003cbr\u003e• ALPS “Blue Velvet” volume control\u003cbr\u003e• configurable 4Ω \/ 8Ω speaker outputs\u003cbr\u003e• can be used as a power amplifier\u003c\/p\u003e\n\u003cp\u003eDesign and performance:\u003c\/p\u003e\n\u003cp\u003eThe amplifier is built around the 2A3 triode, a valve known for its linearity and natural tonal character. Unlike lower-powered single-ended designs, the push-pull configuration here provides increased output and better speaker control while retaining the signature triode sound.\u003c\/p\u003e\n\u003cp\u003eA choke-loaded driver stage allows the 6SN7 valves to deliver a full and stable signal to the output stage. This approach improves tonal depth and dynamic expression, giving instruments a strong sense of body and presence.\u003c\/p\u003e\n\u003cp\u003eMaterials and construction:\u003c\/p\u003e\n\u003cp\u003e• 2A3 output valves\u003cbr\u003e• 6SN7 driver valves\u003cbr\u003e• twin valve rectifiers\u003cbr\u003e• choke-smoothed power supply\u003cbr\u003e• SCR polypropylene capacitors\u003cbr\u003e• selected carbon film resistors\u003c\/p\u003e\n\u003cp\u003eThe power supply uses twin valve rectifiers with choke smoothing, helping to maintain stability and reduce noise under varying signal demands.\u003c\/p\u003e\n\u003cp\u003eSound characteristics:\u003c\/p\u003e\n\u003cp\u003e• rich, holographic soundstage\u003cbr\u003e• strong midrange presence with natural tone\u003cbr\u003e• improved bass control compared to typical triode designs\u003cbr\u003e• high level of detail and texture\u003cbr\u003e• engaging, immersive presentation\u003c\/p\u003e\n\u003cp\u003eThe 2A3 design is known for its ability to preserve musical structure and emotion, offering a highly involving listening experience.\u003c\/p\u003e\n\u003cp\u003eBuild and usability:\u003c\/p\u003e\n\u003cp\u003eThe amplifier includes three line inputs for system flexibility and uses a high-quality ALPS Blue Velvet potentiometer for volume control.
