Кстати, случайно нашел инфу… тут любитель ламп сравнивает Теслу 60-70-х не много не мало с Telefunken E88CC !!! И каково же удивление насколько они внешне похожи, как два близнеца!
Но по тексту отмечает, что далеко не все Теслы е88с такие, он делает акцент на конструкцию лампы а точнее на “серое” покрытие “Gray-Plate” которое применялось для охлаждение в Tesla и Telefunken, но тем не менее, в последующем Тесла перестала его применять…в целях экономии…
Лампы также , как и мои с маркированным кончиком! И ценой под 300 USD за пару!
"“TESLA” VERSUS “TELEFUNKEN” INNER-CONSTRUCTION COMPARISON
You can see that the Tesla E88CC (left side) is quite identical to the Telefunken E88CC (right side) construction!
If you are NEW to tubes, here are some important facts to help you make your decision:
Notice that the Tesla tube has the exact “Gray-Plate” material on the cooling fin right below the electrostatic getter-shield. This GRAY coating is used to deflect the heat away from the center anode plate of the tube, and keep it cooler and perform better. Both Telefunken and Tesla agree! We see inferior constructed tubes and newer production tubes WITHOUT this “Gray-Plate” coating - to lower cost of production - but an an expense, to you, without this heat-reflective coating tube longevity is shortened and performance is sacrificed! Look for E88CC tubes with “Gray-Coating” or Gray-Plates as commonly referred to.
Interesting fact about these Original Military Gold-Pin “Red Tip” 6922 / E88CC tubes is that with each initial test - they RISE in mA and Gm! This means the vacuum is STRONG and the emissions are HIGH! Just take a look at the ACTUAL Amplitrex AT-1000 Test Result pictures below!
The SOUND of these tubes are Phenomenal! These red-tips are the HIGHEST ECHELON of the Tesla E88CC extinct production. To me, they sound and are made with the same high quality as Telefunken, only they have “musicality” and a “liquid” sound, where to me, the Telefunken are quite bland and too neutral.
These Tesla Red-Tips perform with a clean, smooth, rich liquid sound, and the Bass response if phenomenal. Beautiful looking and Beautiful Sounding tubes!
The Tesla perform better in dynamics, and are a more musical-sounding tube - the instruments just sound more realistic and live, than the overly-neutral Telefunken E88CC."
