Things have come together on the Philco! Found the weak signal was caused by two 470K resistors in the tuner. One of them was open, and the other was reading nearly a meg. Signal is good and strong now.

Changed all the caps on the verticle/horz board. Previously, I had left those because they had already been changed before. Raster has now opened up covering the entire screen with a great picture.

Noticed that the vertical hold seems touchy. Gotta work with it to get a lock, and after the set runs for about an hour, it drifts and starts rolling. Great... just when I thought I was finished! I'm a little surprised it's having this issue being that so much has been changed in the sync and oscillator section. Swapping tubes with new ones had no affect. Oh well... I'll find it later.

I starting to think that perhaps Philco should have come up with another name for this series other than Diamond D. This set had many problems to be corrected. It also looks like it's had several service calls in the past considering the number of tubes that had been changed (all but one). It's had several caps changed in the past, and also the CRT. In addition, Don has pointed out a few failures to look for that was common for this series. With all this being said, maybe Philco should have considered naming it the Philco Cubic Zirconia D!
