BROADCASTING.

USING SCREENED-GRID VALVE.

Many amateurs who are familiar with neutralising and its uses in different cases seem to be somewhat in doubt as to the puaitlon when a screened-grid valve is used.

ANSWERS TO INQUIRIES.

THE CHINA MAIL.

"J.G." atates that having occasion to examine his set during reception he found that one of the valves was very warm, and that one of the grid bias tappings had come away from the grid battery. He wishes to know if the omission of the grid tapping was the cause of the valve becoming hot.
