Well these filters are confusing. After being certain I had the correct bandwidth, the replacements are far too wide. It is confusing because the original part number, specc'd 6 kHz is barely if at all traceable. Then the question is that 6 kHz audio bandwidth (for use in AM mode) or total bandwidth. So I purchased filters with spec +/-6 kHz or 12 kHz total bandwidth. They work well in the set, and are properly centered at 455 kHz but are obviously wide. It seems I should have bought components with +/- 3 kHz. Without much expectation, I looked closer at the very blurry schematic in the service manual, this has a part number that is different to the code on the actual filter case, and the required spec is obviousl. Now a replacement is on order, so more waiting... but it should be right.
