Marconi and Osram Valves
Nour issue of October 19 there was reprinted from an Australian journal a paragraph to the effect that the Marconi type screened grid valve was to undergo a change. We are informed that this is incorrect, The success of this valve has been so marked and the demand so great that there is no immediate possibility of this type of valve being discontinued.
The same position obtains in respect of the Osram screened grid valve. Noa change is contemplated. ¥
