NEXT WEEK'S FEATURE FOR CONSTRUCTORE
A SEPARATE RF UNIT FOR THE UX222 VALVE Next week will be described the construction of a single-valve unit employing the new shield grid valve. This circuit was recently published in America, and when a copy reached ‘‘Megohm" he decided to build the unit at once and test its value. The unit does ali that is claimed for it, arid in a test upon an ordinary fourvalve Browning-Drake, about double the usual volume was obtained. This will suit many constructors who do not wish to go to the length of constructing the receiver now being described, but which is, nevertheless, strongly recommended as a quality receiver much ahead of the urtshielded type which has hitherto been constructed. The unit, though specially adapted to the Browning-Drake, can be attached to practically any receiver.
