I have a Systron Donner frequency counter that uses Nixie tubes. The
counter works fine but I am forever replacing the Nixie drivers
74141s. I started to use it this AM an one was out. Is there a
replacement for the 74141, I couldnt find one, or is there a circuit I
could build on a DIP header to replace them. I could probably design
one but I wanted something tried an tested as I dont want to put my
counter board at more risk than I have to.

You might try reducing the current to the nixies by adding some series
resistance. Those 74141s are going to get hard to get. I made a
clock with nixies in the early 70's and it is still working fine.
