For sale a pair of Tungsram ECC83 tubes in very nice condition. They were tested for emission and transconductance with strong results, as you can see on the tags on the tubes. Transconductance was measured at nominal plate current, where these are matching tubes. These are very early made tubes, with robust getter holders, welded plates and black getter. The price will be for the pair! **************************************************** ** ** ** ** ** ** ************************************About the testingsMost of my tubes are tested, but always pay attention to the description in the listing!Vacuum tubes can be tested for variety of attributes, but they are very rarely being tested for everything. I usually test for the attributes I find most important with the specific tube. I take responsibility for these measurements, but not for other attributes that I have not tested!Also keep in mind that when measuring vacuum tubes with different test equipment there will always be differences in the results. However, these differences shall not be significant (usually within 15%), and when done right, wont show a bad tube as good, or a barely good tube as very strong. If you are not sure what you need, or how to choose, message me, and I will try to help you make a decision that fits your needs. Tests I do:- Ia / emission test - is the most common test, which shows how strong is a tubes plate current according to nominal catalog data. The tests are usually done on a standard operating point, and these values ????will be shown on a tag, or in the description.Usually above 80-90% of nominal we say it is Strong (or NOS), and above 60% it is still Good.- S / transcondutance test / or GM - is the second important attribute of a tube indicated as mA/V. These tests are done at the nominal plate current, and also will be indicated on the test tags.- Noise test - is made where it is indicated in the description. It means the tube has been tested for weird noises or microphony while playing music.It will be shown on the test tag as a mark. Keep in mind that noise test does not guarantee any sound quality, which is always the product of a specific tube type, brand, Ia and S attributes, and the amplifier as a system. Noise test means that in a simple audio circuit the tube did t make any disturbing noises, hum, and was not microphonic even when gently tapped. (In an audio system many parts, or the setup can couse weird noises, but it is not necessarily coused by the tube, but by certain interferences.) **************************************************** ** ** ** ** ** ** ************************************ShippingThe tubes will arrive to you in a well protected package, and will be shipped within two business days from payment. The package will be sent with priority, and tracking number will be provided. If you find other tubes in my inventory, I will gladly combine shipping, and the cost will stay as listed under 0.5 kg total .For a package that exceeds this weight, we shall discuss the shipping cost. **************************************************** ** ** ** ** ** ** ************************************About meI am a private seller located in the EU. I buy and sell vacuum tubes.Im dedicated to reserving this beautiful technology, and for that purpose I select, test and rate my tubes. I build my own testers, work with them daily, and I know how they operate. I also a test enthusiast, who likes to learn more about tubes and tube testing. I am dedicated to sell tubes as described, and believe these tubes will perform as they should be according to the description.
