About This Listing

we pride ourselves on a proprietary complimentary value-added refurb screening deox process

2 old stock matsu/mullard 12ax7 ecc83 preamp audio tubes, matched pair carefully curated direct japan import + twice tested 

the british supplied expertise and tooling via 'transfer of technology' resulted in several critical audiophile advantages:

same anodes, micas, electrode geometry, glass envelope, spot welding, grid wire spacing and cathode processing chemistry!

take your listening experience to a higher level of 3-dimensional engaging detail and immersive harmonic imaging

transform sound reproduction across multiple genres w/ more realism, rich bass and holographic textured resolve

translucent highs and warm tone euphony, live-concert style delineation between instruments vocals and percussion

full conductance test 94/92~94/92 % mutual gm (65%)+ important life test pass! = longetivity indicator

our special gm output test applies real world 225vdc voltages w/ filtered dc, plus an impeccable gas test and leak/short check

gm scores relate to current-transfer ability, where gain relates to signal amplification ~ a subtle difference based on voltages

give several sessions or up to 100+ hours w/ your specific amps voltage to settle in (break-in is important)

ships well packed worldwide ~ several pairs in stock! singles or quads upon request

authentic vintage hifidelity audio curation
