walid Posted September 7, 2005 Report Share Posted September 7, 2005 How can I identify IF transformers like this one: 0020070P0N2this is what written at its outside can.I put these numbers in google for search, the results are nothing.can ay one help me please I want to know everything about it like i/p and o/p impedances, turns ratio, ...etec thanks walid :D Quote Link to comment Share on other sites More sharing options...
waferstar Posted September 7, 2005 Report Share Posted September 7, 2005 i/p means Input Impedances: the Impedances which is measured from the input side;o/p means output Impedances: the Impedances which is measured from the output side;turns ratio measns the retio between input voltage and output voltage; Quote Link to comment Share on other sites More sharing options...
walid Posted September 7, 2005 Author Report Share Posted September 7, 2005 thank you very much for this valuable information !!!!!!!!!!!!!!!!!! Quote Link to comment Share on other sites More sharing options...
Staigen Posted September 7, 2005 Report Share Posted September 7, 2005 Hi walidI got i good laughter when i saw the reply from waferstar :) :D ;DBut, what type of if transformer is it? AM or FM? Transistor to transistor? IC? Detector or intermediate? Coming from a junked radio? Oscillator coil? You see, it is many questions. The numders are probably house numbers and are not easily detected.//Staigen Quote Link to comment Share on other sites More sharing options...
audioguru Posted September 8, 2005 Report Share Posted September 8, 2005 I got good laughter when i saw the reply from waferstar.Me too, but I think he means for Walid to test those spec's of the transformer.It would be a pretty big job. I would just purchase a transformer I needed and maybe replace it later with the unknown one to see if it works. ;D Quote Link to comment Share on other sites More sharing options...
Staigen Posted September 8, 2005 Report Share Posted September 8, 2005 Why didn't he write that then?//Staigen Quote Link to comment Share on other sites More sharing options...
