For sale here is a tube and the plastic frame / housing from a Sony Trinitron Multiscan 200sx, tube model m41kka16x. No other internal electronics! The board is fully removed and gone. This tube looked pretty good to me and was tested working.
I read that this tube is also used in a Next display,Trinitron CPD-17F23, and possibly an AppleVision display. Make sure of compatibility before you order.
No returns; I do not guarantee functionality! But I am telling you in good faith it was a working part without any major defects.
