SOLD! I HAVE A SPARE JJ ECC83S HIGH GAIN 12AX7 TYPE TUBE FOR SALE. IT IS NEARLY NEW; IT CAME WITH AN AMP THAT I BOUGHT AND I USED THE TUBE IN THE INPUT POSITION FOR ABOUT 50 HOURS.
I TESTED THE TUBE ON MY RECENTLY CALIBRATED HICKOK 6000 TESTER AND IT IS NEARLY PERFECTLY BALANCED, IT READ 1300/1350 ON THE 3000 Mho. SCALE. NEW TUBES SHOULD READ 1250 PER SIDE. THE TEST RESULTS ARE GOOD TO HAVE BECAUSE WITHOUT THEM YOU NEVER REALLY KNOW WHAT EACH SIDE READS.
THIS TUBE IS OFFERED AT $10.00 PLUS $2.50 PARCEL POST.
