Philco 48-2500 projection tv
Hello Gentlemen
Last spring I found a Philco 48-2500 at a flea market for the can't refuse price of $7 dollars. The cabinet was fair to good, but what impressed me was the set was complete. Most of the tubes were vintage philco (4 tested bad). I changed out all the caps and a handful of out of tolerance resisters. I got some great tips from this website, especially from Tom Albecht about going to a solid state voltage Tripler which I installed and pulled the dc restoration tube. The focus became consistent and improved the picture. The problem I have now is a light vertical bar in the middle of the picture. I can move this bar slightly to the left or right by adjusting the horizontal hold control. Could this be a horizontal phase problem ? I carefully went through the damper and horizontal circuits and changed any out of tolerance resisters, but I suspect the problem could be elsewhere. Please check out the picture. I would appreciate any suggestions ! Thanks Keith |
