Does anyone know this tube? No text or etchings. A few mm shorter than an 807. Heater current 0,88 A.
Thanks! I guess a special quality because of higher current and more robust internal construction
What higher filament current?
Your tube: 0.88A, . . . At 6.3V???
807: 0.9A at 6.3V
That is a close as you get with production tube variances.
The same filament current may, or may not, mean it is an 807 (a 6L6 has 0.9A filament current, but a 6L6 is not an 807).
If you think a 6L6 is a good replacement for an 807, just make a 75 Watt CW transmitter, then you try and tune up the Pi filter to a very reflective antenna (reflective, as in it is either 10 Ohms or 300 Ohms reflected impedance to the transmitter). Zap!
The photo looks like 5 pins at the base.

Look in from the base and determine how many elements the tube has, and what pins they are connected to. Is the top-hat connected to the Plate?
The pin-out would go a long way to determine what it is.
