Disassemble Coronado Blocking Filter

Post by hopes2 » Mon Nov 20, 2017 4:35 pm

Greetings,

Can someone please tell me how to?
I believe the ERF may need to be replaced, do I need to make some sort of spanner wrench or?
Lastly what would be the optimum replacement for the ERF?

Thanks,

Dan

Oops, thanks for the reply.

Bf10 that has a hazy area on the interior side of the ERF.

Thanks again!

Pin wrench will remove the retaining ring and the ITF filter just drops out.
The Maier ITF is a direct replacement.

Thank you, I was able to unscrew it with my fingernail.
Maier replacement ordered.
Have a great Thanksgiving!
