rahulan999 you sun of a gun!
I got the last 2 available in some store in Germany, don't know if there are more in that country.. mine were made in Taiwan, the radios are working well, so am sure they are good quality.. So what are you going to do with all those TE5711's? Just display them and tease those who are looking for them?
I think the next step for you is to make a Stereo receiver and be proud of your work.. You can use the close-up view on my page to get an idea of the layout.. Well good luck if you attempt this project! ;D
