The Tom Evans Linear A and Linear B amplifiers are truly revolutionary, groundbreaking designs.
Both the Linear A stereo amp, and the Linear B monoblock amps are ultrawide bandwidth designs with vanishingly low levels of distortion. More importantly, unlike some other amps with those same two qualities, these amps are incredibly involving and a joy to listen to.
The Linear A is a single ended, Class A, ultralinear stereo amp with a power rating of 25WPC. Four EL84 tubes per side, in parallel, create a composite tube with characteristics almost identical to the legendary Japanese No.10 tube. The amp measures as an almost perfect model triode, promising to deliver the often sought but rarely realized linearity benefits of triode topology without it’s usual limitations.
Paired with an appropriate speaker, this amp can do it all in a way nothing else in our experience has ever been able to do; luscious midrange combined with rarely realized frequency extension. The absence of distortion has to be (not) heard to be fully understood. The clarity and detail retrieval are astonishing, but not at the expense of musicality.
