I have looked at the Ameritron (RF Parts RFC-3) choke and Im not sure it will fit.  I am ordering one, but wanted to see what others have used since this seems like a common failure.   I have 6 Titan 425's here and have 3 of the amps that need the choke replaced.  Most failures have happened on 15 meters.

Rich, my original (S/N 425-00516) Titan-425, smoked the plate choke right after I purchased it in May 1990. I believe the replacement is not continuous spacing but has several sections to avoid a resonance found in the early plate chokes.

See http://www.w8ji.com/rf_plate_choke.htm for plate choke theory, design, and testing.
