I guess I should know better by now.
My 48-482 just didn't sound good on FM and didn't pull in many stations so I thought I'd go over the alignment again, now that my good sig gen is working.
Bad mistake. As I went to adjust one of the cans (C403) as soon as I touched it I lost my tone and the set went michrophonic. If I tapped it it would work briefly.
OK, so I removed it and opened it up. I tested the mica cap inside and it was within specs. I checked the trimmer and couldn't see anything so I gave it a quick spray with Deoxit and reassembled it and reinstalled it. Nothing!
I managed to get the cover off while it was still connected and when I touch the top of the IF transformer (the ceramic part), I get a tone. if I put a screwdriver to the bad trimmer and touch the blade I get a tone.
What did I do now and how can I fix it?Icon_crazy

Thanks,
