[mancave]

fenbach, I've made a few more discoveries. The first is that the phono transformer still does not work. The second is that, if I bypass the transformer, feed the output from my phone directly into the line for the phono unput, and turn the radio volume all the way up, I can faintly hear the music playing. I took apart a wall wart and used the little transformer inside it as a stepup transformer and that made quite an improvement, although it is still not nearly enough. The volume of the radio has to be turned up to a very high level. I need to find a transformer with similar characteristics as the original. Any thoughts on that? The schematic is a little blurry so it's difficult to work out the original specs, but it looks like the primary measures .8 ohms while the secondary measures 5800 -- that's quite a difference!
