We have literally hundreds of thousands of tubes in our warehouse, so please continue to check our listings as we will be listing more electron tubes each week. Tubes have been tested on one of our calibrated Bitmatic (Western Electric KS-15874-L2) computerized testers and are guaranteed good, test results as follows (tube number will be marked on the inside of the top flap of each box): Tube 1: 4550 umhos where 2500 - 5000 umhos is the acceptable range on the tester Tube 2: 4700 umhos where 2500 - 5000 umhos is the acceptable range on the tester Tube 3: 4300 umhos where 2500 - 5000 umhos is the acceptable range on the tester Tube 4: 4500 umhos where 2500 - 5000 umhos is the acceptable range on the tester Tube 5: 4350 umhos where 2500 - 5000 umhos is the acceptable range on the tester Tubes 1 and 4 as well as tubes 3 and 5 would make nicely matched pairs. All our tubes are tested and guaranteed by us; we only test tubes on one of our quality calibrated mutual conductance testers, NEVER on an emissions tester. The testers we use are Phil Frakes's Bitmatic computerized Cardmatic testers from Tubesontheweb, the specific models are Western Electric KS-15874-L2's which were made for Western Electric by Hickok; we currently own two of these testers. Our backup testers which we use occasionally are military TV-10D/U's. For specialized tests, we employ one of our VTV Dual Triode Characterizers (for preamp tubes) as well as a Maxi-Matcher (for power tube matching). Tubes are guaranteed for 90 days, refund or replacement our choice. Thanks for looking at our auction and be sure to check out our other auctions for other tubes that may be of interest.
