Thanks,
I looked at that. It is the CFJ455K 15... The K12 and K5 need to
see a 2k input and output. I am not sure what the K15 filter uses. I
am trying to resurrect a TS-830S. I received it sans any filters.
These are the stock 455 filters. I need to get a filter in there to
see if it still works. I really did not want to sink a bunch of cash
in a Collins or Inrad filter and then find out the radio is not
worth fixing.

Rick -

The Yaesu FT-817 and Icom IC-703 use the MuRata CFJ455K ceramic filter.
So
a Collins mechanical or Inrad upgrade like shown at W4RT would qualify

Unless it is an ugly duckling .. TS-830 repair should be straight forward

I think most of the Murata filters are either 1.5K or 2K input and output

In the second RX of the Yaesu FT-1000(D) and the FT-1000MP you will find a
Murata 455 kHz ceramic filter.
This will be the Murata CFJ455K '15', '13' or '5' filter.
