I thought I'd post a photo of the networks that I just finished. The only one I had to put a 600 pf mica on the backside was N3 because of lack of room on the front. I would have loved to have used smaller components like the ones Bob uses in his. Just had to work with what I could get up here. The local electronics store closed a few months ago and hopefully will be back at a new location soon. I also picked up a Blonde Holiday with a 21" screen over the weekend. It is in pretty good shape, missing the horizontal knob and the tuning knob is broken where it goes on the shaft. Looks like someone had the main board out a long time ago but didn't change too much. A few black beauties are split open. They did a sloppy job, also there is a booster on the picture tube, so I'm not sure what that means as far as the shape of the picture tube goes. I don't have a picture tube tester. I mounted some of the electrolyics on the main board but still need a 100mfd to complete it. I installed 2 new octal sockets. The others, I just tightened the pins on them. I ended up using 3- 1300 pf polys for N3 rather than 2- 1200's and a 1600 pf in the middle. The total capacitance was about 50 pf under 4000. Using the 2-1200's and the 1600 would have put it about 50 pf over 4000. Hopefully it will be close enough. I just have to coat them with epoxy and make them look rusty like the originals.
