WOW!!! Frustration. I found a broken lead inside the IF Interstage Transformer on my Silvertone 1828. It's no longer long enough to make a solid re-connect so I am trying to solder another piece of wire to it. This is that really small coil wire. I can wrap another piece to it and make the radio work but any movement knocks it out. I can't get the wires to accept solder. Tried a dab of flux, make sure they're clean etc. How does one repair something like this? Thanks!

Try Acetone or nail polish remover on the wire. It will melt off the enamel coating. Solder, then glue in place.

:Okay that's worth a try. What if I wanted to replace the whole transformer? I'm not sure but I believe this would be the 1st IF transformer. Can it be replaced with another 1st IF transformer from another radio? I've got another one that is physically the same and even fits inside the existing can. How are these things rated? 455KC, 456KC etc.? Thanks!

i think as long as the resonant frequency is the same you should be good. what i dont know if all these cans are 1:1 ratio or otherwise.

:Well trying to repair this old one isn't going too well. I'm going to try to replace it with this other one. The only test I can do on these things is resistance. There is a 1 ohm to 3 ohm difference between the old coils and new ones. Is this enough to make it not work and can it be compensated for through adjustment of the trimmers?

:UPDATE: I installed the new IF transformer and it works just fine. Nice little learning experience. Thanks for all your help.
