1962-64 Vintage MATCHED Pair of Amperex made for Hammond ECC83 / 12AX7 Twin Triode tubes. These are special, low-noise versions ideal for Hi-Fi Audio use. Both tubes were made at the famous Heerlen Factory in Holland. One acid-etched code reads: "I65 Delta2A3" and the other reads: "I65 Delta4G2". Both tubes are identical in construction with short, ribbed plates, but the 1962 tube has a slightly larger "Halo" getter making it more collectable.... These tubes were forwarded to Hammond where they were put under further testing for noise and hum. Very CLEAN tubes with clear lettering and nice straight pins. Test VERY STRONG and balanced! Results:
TUBE 1: 1, 600 mhos (100%) / 1, 600 mhos (100%)TUBE 2: 1, 700 mhos (106%) / 1, 600 mhos (100%)
Average NEW / NOS spec for this type is 1, 600 mhos (100%) / 1, 600 mhos (100%). Comprehensive computer-generated results sheets included!
A little bit about me and my valve testing business..... I started in the tube business as a small hobby in 2012 testing and selling a few small radio tubes. Now it has turned into a big hobby as I have sold 1000's and 1, 000's of tubes to many happy customers. I personally inspect and fully test each tube and offer a 30-day unconditional 100% guarantee on all my tested tubes. I am not a store or full-time business, but I take great pride and care in what I do, and your satisfaction is my number one goal. I have two of the best tube testers ever made that I use to fully test tubes. The Amplitrex AT-1000 Digital tester and the Triplett 3444 (with digital plate current meter) Tube Analyzer are both mutual conductance testers that can test just about any tube ever made between the two of them and can test for shorts/leakage, noise, gas, emissions, and transconductance. I have an extensive back stock of tubes, so if you have a certain brand or type you are looking for, feel free to contact me. Thank you for choosing Valves-Tubes!
