Well, first power-up went way better than I had even hoped. Using a metered Variac, I was rewarded with no bad noises, smells or smoke. And at 115 Volts, I was rewarded with FM radio music in the speaker and a raster! The 12JP4 has the usual ion burn in the center, but no ion trap to adjust!


I hooked up the cable box with output on channel 4, and it didn't take long to get its first coherent image in probably several decades:


Vertical and horizontal lock are rock steady. I made all the usual adjustments. I ended up getting the vertical linearity somewhat better than in this screen shot:


The Inductuner is a bit scratchy, but the best picture and sound coincide!
Here are a few more screen shots.





I'm still marveling at how well this set is working after shot gunning all the caps. The only tubes I've tested are the horizontal output, HV rectifier, damper and both 5U4's. Now, I'll test the rest of the tubes and clean all the pots. Oh, and the AM radio works fine too!
