audioguru Posted January 6, 2006 Report Share Posted January 6, 2006 Hi Ryan,Welcome to our forum. ;DThe transistors in the transmitter don't have bias current so their output will be zero until a certain input level is reached. The result with enough input level is extreme distortion.The receiver applies a fairly high current through your headphones which probably burned them out!

ante Posted January 6, 2006 Report Share Posted January 6, 2006 Hi Audioguru that was post number 5000 :o so good luck with the next 5000! ;D Quote Link to comment Share on other sites More sharing options...
audioguru Posted January 6, 2006 Report Share Posted January 6, 2006 Hi Ante,Thanks. I was near 5000 and I tried to cheat a little. I corrected spelling in some old posts hoping that each revision would be counted. Nope.Why are there so many lousy designs on the web? ???There are too many for us to fix. Many use old obsolete parts.Maybe the circuits on the web should all be deleted or re-formatted then only good designs posted. ;D Quote Link to comment Share on other sites More sharing options...
ante Posted January 6, 2006 Report Share Posted January 6, 2006 Hi Audioguru,Yes it’s true, quite a few projects use obsolete parts or hard to get parts but often they can be substituted with modern parts. I think most circuits work even though many can be greatly improved by an ace like you. ;D The once which don’t work at all must be made by mistakes or typos. 8) Quote Link to comment Share on other sites More sharing options...
