There simply is not a canned answer for many of the problems you'll encounter, not even in advanced text books of the past, so you need to become quite well versed in the basics in order to find your own way. The B&K 1076 I mentioned earlier - being it's old, all tube, and quite a complex piece of test equipment, I fear if it has stopped working when you get it, or stops working at some point, you will just have wasted the shipping money on a useless paperweight. No one here is scolding you, but there simply is not a way for any of us to help you advance beyond your own willingness to teach yourself.  |
And I did finally figure it out on my own. I realized that some of the electrolytic caps that I didn't replace yet at that point were part of the deflection circuitry so I decided to finish replacing the electrolytics and sure enough it fixed the issue.
As for the Magic Smoke escaping issue I figured out it was the output transformer had gotten smoked, because when I went to test it after my initial recapping (replacing the easier to access electrolytics and paper caps) to check my progress with getting some sort of recognizable raster that wasn't deformed/collapsed looking, I forgot to connect a speaker to the output transformer and I think that's what the magic smoke came from.
Thankfully i have some spare Zenith output transformers that I had salvaged from that old Zenith Console Stereo I picked up for parts, but they have three wires on the primary side rather than just two wires like the one that's in there right now that had burned up.
They have a brown, blue and red wire lead on the primary side as opposed to just the red and blue wires on the original transformer.
If I were to use one of the replacement output transformers that has the three wire leads on my small Zenith TV in place of the burned out transformer, would I just cut the brown wire off the transformer and use just the red and blue wire leads, like how it was done on the original output transformer?
Any help with this issue would be appreciated.
