FOR SALE:
2 PIECES 6H30DR TUBES ( 6Н30П-ДР )
DATE CODES: TUBES: 9101 & 9102
THESE TUBES WERE CAME FROM A BALANCED AUDIO TECHNOLOGY VK-55SE AMPLIFIER, THAT LOOKS LIKE IT WASN'T USED, FROM THE WAY IT WAS STILL PACKED IN THE FACTORY BOX, BUT NOT 100% SURE IF THESE TUBES WERE EVER USED IN THE AMP OR NOT.
THE TUBES LOOK NEW, WITH NO NOTICABLE SIGNS OF FADING ON THE 'BALANCED AUDIO TECHNOLOGY' LETTERING ON THE GLASS, IN WHICH THE LETTERING DOES FADE FROM NORMAL USAGE OVER THE YEARS, BUT THE LETTERING ON THESE TUBES LOOK VERY EXCELLENT, AND THE TUBE GLASS IS VERY CLEAR TRANSPARRENT, WITH NO DARKENING, OR SADES TO THE GLASS, SO THAT'S AN INDICATION THAT THERE'S NOT MANY HOURS ON THESE TUBES AT ALL, OR EVEN A POSSIBILITY THAT THE TUBES MAY NOT HAVE EVEN BEEN USED AT ALL, BUT I CAN'T BE SURE OF THAT, SINCE THE AMPLIFIER WAS NOT IN A SEALED BOX.
THERE ARE SIGNS OF TUBE SOCKET MARKINGS ON THE PINS, BEFORE I EVEN PUT THE TUBES IN A VK-32SE FOR SOUND CHECK, SO, IT'S A POSSIBILITY THAT THE TUBES MAY HAVE BEEN TESTED AT THE BAT FACTORY FOR TESTING AND SOUND GRADING? REGARDLESS, THE BALANCED AUDIO TECHNOLOGY PRINTING IS STILL DARK AND FRESH, SO TO ME, THEY DON'T LOOK LIKE THEY ARE USED MUCH AT ALL, OR EVEN AT ALL.
IF YOU NEED SETS OF 4, OR SET OF 8 TUBES, THEN PLEASE SEE MY OTHER EBAY LISTINGS.
DON'T WAITE, GRAB THEM WHILE THEY LAST!
AS YOU KNOW, THE MILITARY 6H30DR TUBES HAVE BEEN LONG OUT OF PRODUCTION, AND EVEN USED 6H30DR TUBES ARE HARD TO COME BY THESE DAYS.
BALANCED AUDIO TECHNOLOGY HAD A HUGE STOCK OF 6H30DR TUBES, AND THEY WERE HAND SELECTED AND TESTED TO ASSURE LOW NOISE, AND PROPER PERFORMANCE BY THE BAT COMPANY, FOR THEIR SE PREAMPS AND SE CD PLAYERS.
IN 2006, WITH THE NEW RELEASE OF THE VK-32SE, VK-52SE, AND REX-2, IT WAS A $300 PER 6H30DR TUBE OPTION, TO ORDER IN THEIR 'SE' SERIES PREAMPS AND SE CD PLAYERS. BUT THAT WAS THE PRICE FOR THE 6H30DR TUBES FROM BAT, BACK IN 2006! I WOULD GUESS THAT THE PRICE FOR THE 6H30DR TUBES WOULD BE MORE TODAY, OR MAYBE NOT AVAILABLE FROM BAT ANYMORE.
THESE ARE LATE PRODUCTION OF THE ORINGINAL PRODUCTION 6H30DR TUBES FROM THE EARLY 90'S, AS SHOWN IN THE FIRST PHOTO, SHOWS THE DATE CODES OF THE TUBES. DATE CODES ARE 9105. '91' = 1991, 05 = 5th MONTH OF THE YEAR.
AS YOU CAN SEE IN THE SECOND PHOTO, THE TUBES HAVE SOME REMAINING STAMP OF "BALANCED AUDIO TECHNOLOGY" ON THE TUBES.
AS YOU CAN SEE IN THE THIRD PHOTO, THE GETTER RING IS LARGE, WHICH INDICATES THAT THESE ARE REAL 6H30DR TUBES, NOT FAKES.
THE TUBES HAVE ALL THE SIGNS ASSOCIATED WITH THE ORIGINAL PRODUCTION OF 1992, AND BEFORE.
THE PRODUCTION OF THESE TUBES WERE RESTARTED IN 1999 AS COPIES, BUT NOT MADE EXACTLY THE SAME AS THE ORIGINAL DR TUBES, AND THE DIFFERENCES ARE EASY TO NOTICE.
THE COMMON VISIBLE DIFFERENCES BETWEEN THE ORIGINAL REPRODUCTION 6H30DR'S ARE:
1) THE TUBES NUMBER IS 6Н30П-ДР,
2) THE PLATE WINGS, THAT SHOW DARK UNIFORM SURFACES, FREE FROM TOOL MARKS.
3) THERE ARE NO PENCIL MARKINGS ON THE BOTTOM MICA INSULATORS.
FOR MORE DETAILS, THAT EXPAIN THE DIFFERENCES BETWEEN THE ORIGINAL AND REPRODUCTIONS OF THESE TUBES, LOOK AT THE WEBSITE:
http://www.aca.gr/index/hiend/hiendArticles?row=1988
NO WAY OF REALLY KNOWING HOW MANY HOURS ARE ON THESE TUBES, IF ANY, BUT THE VISUAL SIGNS OF LOW USAGE ARE THE 'BALANCED AUDIO TECHNOLOGY' LETTERING IS STILL NICE AND DARK, NO SIGNS OF THE LETTERING FADED FROM LONG TERM HEAT.
THE 6H30DR TUBES HAVE A FACTORY RATING OF 10,000 HOURS.
FOR EXAMPLE, IF THE TUBES HAVE 100 HOURS ON THEM, THEN THAT IS ONLY 1% OF THE LIFE USED ON THE TUBES, WITH 99% LIFE REMAINING!
THESE TUBES HAVE BEEN TESTED IN A BAT VK-50SE PREAMP (THAT I ALSO HAVE FOR SALE) FOR THE PERIOD OF TWO DAYS, AND PERFOMING WITH CLEAR SOUND.
I DO NOT HAVE A RUSSIAN MILITARY TUBE TESTER THAT CAN TEST THESE RUSSIAN MADE TUBES FOR EMISSION.
BUT, ALL 4 TUBES DID COME OUT FROM THE SAME VK-52SE, AND THESE HAVE MATCHED DATE CODES.
THERE'S 2 MORE SETS OF 4 6H30DR TUBES FOR SALE, THAT CAME OUT FROM A VK-52SE PREAMP, IN MY OTHER EBAY LISTING.
