Fortunately we
could find out information about data and origin of the before
mysterious ECH4G.
Fortunately we could find out information about data and origin of the before mysterious ECH4G.
Now the secret of this ECH4A is yet to be solved.
Because of the straight bulb shape the ECH4A may probably be an Octal version of the E1R ?
Can anybody confirm this, e.g. by comparing the data ? Even checking the heater current will give some evidence, since the heater current of the E1R is only 0.2 A, while the heater current of the normal ECH4 is about 0.35 A.
Best regards,
Jacob
