crown jewel early panasonic! highly revered for their incredible sound reproduction, and often compared to mullard sonics
back then, mullards vacuum tube empire was vast, setting up advanced manufacturing facilities worldwide, along w/ philips
this famous 'transfer of technology' provided legendary tube-era metallurgy, engineering, quality, longetivity, and low noise
this same british cathode chemistry process, anode plate supports, electrode geometry + glass, resulted in coveted playback

described as a rich full tonality w/ plenty of detail, sweet warm balance, dimensional presence, all w/ translucent highs
this elegant musicality is expressive, and clean, all w/ excellent stage dynamics (and often rich overdrive in guitar amps)
this quite versatile vintage classic, reproduces a smooth extended sound profile, reveals lush mids, + has a defined low-end

tweak, tune-up, and transform your harmonics, measured feedback, warmth, tonal articulation, and system definition
elevate your clarity across genres and musicality types, w/ richer bass depth, and more textured revealing acoustics

take your listening experience to a higher level of immersive engagement, especially old school brass and percussion


the high power 7189 is an audiophile 6bq5 el84 plugin, w/ higher max ratings, and cleaner + sweeter, all w/ lower gain
this industrial premium 6bq5 upgrade, utilized 6rp15 tech, w/ overall less edge + compression = a long life pure performer
