HP D2804 monitor equipped with crt Samsung M34KUN35X03. Is it possible to substitute with Toshiba M34KQA23XX06?
I save all the picture tubes from monitors I junk out, and substitute freely. Since the convergence is nearly impossible to set up, I leave the yokes on the tube. I can usually lay the chassis on its side and connect up the anode, yoke and ground wire (don’t forget the ground wire!) without having to do the whole swap until I can see if the yoke is compatible with the existing drive stage. Surprisingly, about 75% of the time the tubes present no problem and the swap is relatively easy.
