| Descripción |
The heater current of the Tungsram ECH2 is only 0.35A compared to 0.95A of the original Mullard ECH2, which points to a considerable modification of the tube.
Since the operating data of the ECH2 differ only insignificantly from those of the ECH4, one can assume that the system of the ECH4 has been used here, to which the specified heater current 0.35A also fits.
The big bulb was probably chosen to achieve the height of the original Philips ECH2.
