(Resending using plain text.)
I started reassembling the coils in the RF deck of my R-390 and discovered some damage the one of the pins on Z221 (upper left pin in the first image attached). The spring contact assembly is missing entirely. I notice that the center pin is not connected inside the housing but I think it would be a significant effort to try to remove both pins and replace the bad one with the good one.
When I disassembled Z214, I noticed one of the small fingers had broken off (second image attached). The finger was left where the coil plugs in and I saved the finger. I may have rocked the can just a little too much (it was very difficult to remove) and that may have broken that finger. While I think that pin will still make sufficient contact, I may still try to solder that finger in place.
What are my possible options for Z221? I presume there's not a stash of those coils (Z219, Z220, Z221 as I think they're all the same?) somewhere. Any ideas?
Something tells me the combination of the broken slug I repaired and getting Z221 properly connected (and a fresh alignment) will make quite a difference for this radio.
Thanks,
