Philco 48-2500 Restoration Blog

[John Folsom]

Here is an interesting Philco tidbit. Philco made this kit to convert your 48-2500 projection set to a code 125 model. This is a 1X2 based tripler HV power supply sub assembly. I assume it is intended to replace the older 1B3 based tripler.

In addition to installation instructions, they have a sheet of service tips. Of interest is the suggestion that the DC restored tube be removed. This improves the focus performance in changes from light to dark scenes. They state the improvement in focus will more than offset the disadvantages of not having DC restoration
