      Nothing on the seller but; The prices on preamp tubes are just rediculous these days. 10 years ago you could buy the JJ’s for under $10.

    • Excellent product quality.

      Each vaccms tube was tested and 4 test values were marked one ach tube box. Tubes were realy nice in appearance and the pins were extremely clean and shiny. Initial listening test was stisfactory even before required aging time. User manuals/specification and infomartion pamphlets included in the package indicated sellers interest in the product quality. Excellent prouct !!

    • Try 'em

      These have a unique sonic signature. Extended at both ends but tight bass. A little lacking in bass heft but has good detail and soundstage. Good match if your amp uses EL34 tubes. I prefer the Tungsol 12ax7 in my setup.

    • Amazing

      I love this tube with all my heart it will forever live in my 10 watt combo. It has No microphonics to speak of and it breaks up alot better than a short plate. Overall a rocking tube.
