[Premium-Rx] Racal 6790 Collins Filter Removal

[Gordon & Lois Duff]

I have three 6790s.  I just purchased at auction an
A24 board populated with 6 Collins mechanical filters.
The item arrived as advertised.  However, I was
surprised to see that the filters were soldered in.
They look like they are going to be a bear to get out.

 

I don't want to swap the A24 board as mine is much
cleaner, probably a later version, and I know it
works.  Any suggestions on removing the filters from
the board?
