Go over the metal bell, slowly withdrawing before switching off the current.

Chris last said he was persuing alternative yokes. I cannot see how a defective yoke could physically cause the pincushioning.

To review: could Chris recap the sequence of events?

Did the origal tube work and display non pincushion?

Did the pincushion only appear on the replacement tube?

Does Chris have a degaussing coil and has there been any update?

Hey guys...sorry I've been MIA. Life showed up really intense. I'll update everything shortly. Nothing has progressed since my last update. Picture is still slightly distorted with symmetrical bends in the vertical and horizontal aspect like it's being pinched top to bottom and side to side.
