    Help with Klipsch k77 Tweeters and Different Volumes

    So, I picked up a pair of Klipsch K77 tweeters, for a yet-to-be defined project. Price was right. Or, at least seemed so. I hooked up both tweeters to a small 15W amp, just to test 'em out. The volume from one was significantly louder than the other. The louder one seemed distorted a bit...

    Detached magnet - simply re-glue?

    Newbie question: The magnet has come off on one side of my Samson SR850 (very similar to Superlux HD668B). Can I simply re-attach it with glue, or is there more to it than that? Is there something else I should check? And if glue, any kind? Super glue? (When I try just placing it and...

    Sony TA-N77ES gets hot and right channel fades out?

    Hi. Just purchased this after years if hunting. The unit runs hot and the right channel fades out... Leaving it to cool down it works again. Could it be the DC offset or the Bias that needs to be adjusted?
