[R-390] Filters

[quartz55]

Well, I don't think I've destroyed it yet.  The coils still measure around 52 ohms on the wires.  I got one of the coils out, it just pulled out with the wires, the tape tab just came out when I pulled on it.  There's a much better  repair link here, but if you look at my pictures, it adds a bit of info.  I wasn't sure where the magnet was.  The filter repair link is http://www.delphelectronics.co.uk/filter390a/ and you can see my pictures here http://s251.beta.photobucket.com/user/DogTi/library/R390A

I'm not sure what was wrong with this filter.  The tiny wire in the center of the bobbin is indeed small, I have a hard time seeing it.  All I've done at this point is clean things up.  There was a bit of detrius in between the metal coils and there is a bit more in there I need to get out.  I'm not messing with the center wires.  I'm not sure if the center wire goes through all the discs, I don't think so, I think I can see it on the top end it attaches to the 2nd disk from the end.  I can't see the center wire on the bottom end between the discs.  I'm thinking I'll have to use a tiny bit of silicone glue to hold the bobbins in place in the copper cylinder since they seem to be loose and the tape is doing nothing.  I see no reason to take the magnets off.  I've cleaned up all the spongy stuff and loose glue around the magnets.

I still measure infinity with my fluke from the bobbin wires to the discs.  I'm hoping just cleaning it up will do something for it.  We'll see.
