Can anyone shed some light on this problem. The core if the T/R relay seems to become magnitized and will not release. If I de-magnetize the thing, it just becomes magnitized again with the next usage. As in one key and it is stuck. I don't have a schematic, but my guess is there is some small leakage current flowing through the coil causing the problem. Is this a bad vox tube or what? Thanks -Pete
