UP FOR YOUR CONSIDERATION IS THIS 

PAIR OF AMPEREX 12AX7 TUBES

WITH YELLOW TIPS

Here is a nice pair of Electrohome 12AX7 tubes with yellow tips that were made by Amperex in Holland.  Date codes are Delta5K4.  The yellow tip typically signifies that they were screened for low noise and were used for medical equipment. These were removed from an Electrohome tube organ.  Labels are in great shape as shown.  These are getting harder to find and becoming very expensive.  They were tested on Hickok 533A tube tester where 1250/1250 is the minimum for a new tube.  They tested at 1450/1350 & 1400/1300. These are well balanced and will sound excellent in your amp.  Ship in plain white tube boxes.

I TESTED THE TUBES ON MY CALIBRATED HICKOK 533A TUBE TESTER AND THE RESULTS ARE SHOWN.  TESTING RESULTS AMONG VARIOUS TUBE TESTERS WILL VARY.  IF YOU ARE UNHAPPY WITH THE TUBES I WILL ACCEPT REFUNDS BUT THE BUYER PAYS RETRUN SHIPPING.
