TESLA Vršovice KT-88 QUAD NOSVery rare Tesla Vršovice Czech Republic Ultra Premium Audiophile tubes!! These are not JJ Tesla tubes!
Tesla Vršovice tubes were also marketed under the KR Audio name (see comparison photo) and currently EAT( EAT retail is $1695.00+ !!).They are made in small quantities to extremely high quality mfg. specs.They recreated the sound of the original Genelex tubes having striking clarity and transparency far above any other modern production tubes. Superb construction and a much harder vacuum during manufacture were two of the many reasons.
They all test new on my calibrated Hickok 533a and in a Williamson amplifier test rig. Gm is matched within 9% across all four tubes. Current in cathode bias test amp measured between 59.5ma to 61ma
gm results 7150, 7000, 7500, 8000, 8500 where average new is 7000
all test ok for gas ,shorts and sounded glorious with good emission
tubes will be well packed, If you need 8 tubes check out my other add for KR KT-88 quad ( same tube) Tubes are being sold as-is, no returns , USA sale only
