Alingning Gang Condensers

ALIGNMENT of gang condensers can be readily checked with a simple tool made from a 5in. piece of ebonite rod with a 1}in. heavy copper wire ring fastened to one end and an old condenser plate fastened to the other end. This tool may be used to add an extra plate to the’ moving plates of each condenser in the gang by placing ifs condenser-plate end in parallel with the fixed plates and touching the. moving plates. If the signal then increases in strength, the condenser is low in capacity and its trimmer should’ be tightened. If the signal decreases in strength the condensers are approximately in alignment. After checking for low capacity, insert the ring end of the too] in the centre of each radiofrequency coil. This should decrease thé signal strength. If the signal increases, the capacity is too high and should be lowered by adjusting the trimmer or bending the outside plate untika decrease in signal is experienced. The condenser-plate test should then be repeated so as to be sure that
