Show when dry cell tubes are used in radio set when dry cell tubes are used in a set the operator should take into account the ampere consumption and provide enough batteries so they will not run down prematurely not more than amperes should be drained from an ordinary six volt dry cell if a tube Is used that consumes 23 25 amperes use nt at least two dry batteries in parallel 0 1 e connected plus to plus and minus to mi minus this will not increase the voltage a 1 volt tube will not get any more voltage from two batteries in parallel than it will from one and there Is r no danger of it burning out tubes th that t call for more voltage must of course have more batteries hooked up in series 1 I 1 e plus to minus tile the more tubes there are in a receiving set the more bat batteries should be hooked up in parallel as the ampere drain Is greater the directions accompanying dry cell tubes should be rend read carefully and voltage and amperage requirements noted |
