Show S SHORT HORT CIRCUITS 00 J A burned out vacuum tube makes an excellent grid condenser all you need do la Is remove your lour present grid condenser and connect the grid terminal on the base of the tube to one end of I 1 the wire that was former formerly ly connected to the condenser then connect a wire to the grid of the detector find and lead it to the plate terminal on an the blon out tube connect the grid leak from the grid to the filament minus or plus plug trial Is the tefa test and be surprised at tile the difference in reception if your B batteries are run down and you are not in the position to purchase now new ones for a few days then place them in a warm warlin oven for a few hours you will find that they will greatly increase in voltage say that a it battery registered 30 volts then after baking jt it will go to about 40 volts or perhaps more this scheme Is not recommended unless in an emergency ns as it Is a rather dirty job and is usually not worth the trouble if you have a potentiometer in your set you will find fand that the set will work a little better bettar if you connect a fixed condenser from the movable arm of tho the potentiometer to one of the tha ends there Is no need of soldering every connection in a radio set in fam fact it Is better riot not to solder some terminals for instance cnstance ns tance it la Is absolutely sary lo 10 solder wires to vacuum tube sockets place the wire under the screw after looping it around and tighten the screw with pliers this holds true with transformers some binding and in fact any con lection that can be cade so t cure without |
