Your post makes no sense whatsoever.

Why should someone who has invested time, effort and money in an expensive existing enlarger system setup throw it all away because of a now-obsolete bulb if a simple way can be found to extend that bulb's life?

I have a wall-mounted enlarger system. And 13 negative carriers, including 5 glass ones. And a 4-bladed masking attachment. And a micro-focusing attachment. And 7 enlarging lenses. And two 3-lens rotating turrets, one for modern Schneider optics and the other for period Kodak Ektar optics. The enlarger is directly mounted to a pair of 4x4 posts intentionally built into the wall and bolted to a concrete floor. The system has been custom modified and critically aligned to project onto a large polished birchwood workspace that was designed to accommodate a 16x20 Saunders easel as well as a 16x20 vacuum contact easel.

I'm supposed to throw all of that away and replace it with someone else's curb trash just because someone thinks I shouldn't even try to extend the life of a bulb?
