One possible remedy for excessive hum is some condition in the detector tube circuit. Try each of the 24 tubes in the detector Becket. A tube that hums in the detector socket, may not hum in the other 124 sockets. In the event of excessive regeneration difficulties, check the position of the grid wires. If too close together, this trouble is liable to occur. Check the .015 mfd condenser on the center of the fuse panel. Also open. 25 mfd bypass condensers.
