Vintage Gray Plate 3 Mica 12AT7 HICKOK 539C TESTED 2ed

Description: Look!! FIRST PLEASE SEE LAST PICTURE FOR TEST RESULTS.AND NOTE THAT THIS TUBE IS SHOWING MIN RESISTANCE IN A SECTION WHICH IS NOTABLE ON THE 539C BUT IS STILL CONSIDERED PASSABLE BY MOST STANDARDS. SECOND, A LITTLE ABOUT THE METHOD IN WHICH MY TUBES ARE TESTED, I TEST ALL TUBES WITH A HICKOK 539C LABORATORY GRADE TESTER, THE MOST POWERFUL AND RELIABLE TUBE TESTER EVER MADE. IF YOU THINK I AM KIDDING OR BLOWING HOT AIR DO A SEARCH ON EBAY FOR HICKOK 539(C) AND YOU WILL FIND THESE TESTER MOST OFTEN GO FOR 2000.00 OR BETTER. THERE IS A GOOD REASON WHY THEY SALE FOR THE PRICES THEY DO. THIS TESTER IS ABLE TO TEST TUBES IN WAYS MOST TESTERS SIMPLY CAN NOT. DON'T TRUST YOUR AMPS TO A GUY TESTING TUBES WITH A HUNDRED DOLLAR UN- CALIBRATED TESTER AND SELLING THEM ACROSS A BED SHEET. INCOMPLETELY TESTED TUBES CAN HURT YOUR GEAR LONG TERM AND EVEN SHORT TERM. NEXT I'D LIKE TO SAY A BIT ABOUT THE MOUNTAIN OF CONFUSION THAT HAS GROWN AMONG THE AUDIOPHILES OF THE WORLD: GOOD USED VINTAGE TUBES ARE GETTING HARDER AND HARDER TO FIND AND SOME DAY THEY WILL BE GONE.THERE ARE NEW TUBES BEING PRODUCED TODAY, BUT NONE THAT HAVE THE TONE OF A DAY GONE BY, MOSTLY BECAUSE THE MATERIALS VINTAGE TUBES ARE MADE OF CAN NEVER BE MADE AGAIN OR DUPLICATED, SO TRY AS THEY MIGHT THE SOUND IS NOTICEABLY NOT THE SAME. SOME DAY NEWER TUBES WILL BE ALL WE WILL HAVE BUT TODAY WE RIDE THE HIGH WINDS OF GOOD FINDS. SO IF YOU FIND GOOD USED TUBES THAT TEST OUT WELL IN ALL FIELDS AND AND HAVE DECENT DYNAMIC TRANSCONDUCTANCE VALUES BUY THEM AS THE DAY IS GETTING LONG IN THE TOOTH FOR THESE OLD GEMS. EVEN VINTAGE TUBES WITH LOWER VALUES STILL SOUND BETTER THEN MOST NEWER TUBES AND CAN STILL BE ENJOYED IF YOU ADJUST YOUR AMP TO MAKE UP FOR THE LOSS OF THE TUBE VALUES. A WEAK TUBE MAY NOT LAST AS LONG BUT MAY VERY WELL SOUND BETTER THEN MOST NEWER TUBES YOU CAN BUY TODAY.I PRICE MY TUBES ACCORDING TO HOW WELL THEY STAND TO THE RIGOROUS TESTING METHOD THE 539C PUTS THEM THOUGH SO IF THE TUBE SEEMS PRICEY THERE IS A REASON .I WILL MOST LIKELY HAVE SOME OF THE SAME TUBES LISTED FOR LOWER PRICES THAT HAVE LOWER VALUES IF YOU WANT TO EXPERIENCE THE SAME TONE ON A TUBE THAT MAY VERY WELL SOUND JUST AS GOOD BUT MOST LIKELY NOT AS LONG.IT MAY TAKE ME A WHILE TO GET THEM LISTED AS I HAVE MANY TO LIST, BUT LIST WE WILL. REMEMBER,,,,, TONE IS A FICKLE BITCH AND VINTAGE TUBES IS HER NAME. WE HAVE BEEN SELLING ON EBAY FOR 20 YEARS SO TAKE A LOOK AT OUR FEEDBACK AND BUY WITH CONFIDENCETHESE ARE PHOTOS OF THE ACTUAL ITEMS YOU ARE BUYING AS WE DO NOT USE STOCK PHOTOS. H.T.
