So the strategy the next time would be to do whatever needs to be done preliminarily, like in this case, the sound discriminator response and the sound IF response but at that point, before getting lost in the weeds of going through each step in adjusting traps and IF transformers, just go to the overall IF/RF response curve and see how well it's aligned. If changes need to be made, then individual transformers, coils, traps etc can be individually targeted to make subtle adjustments to firm things up on the overall trace.
If this TV is so screwed up now it's basically unsalvageable, that's fine. Just this learning experience has been so valuable to me I'd do it all over again! Remember, at the beginning of this, I had never seen a response curve for any TV I've ever worked on. It looks like the reason for that was bad and unreliable equipment as much as my inexperience. Where I am and this workbench is are miles more advanced from a couple of months ago!
I'm not giving up yet. I'll get this broken slug out and find a comparable one to replace it with. I want to get the transformer, T-103, out tonight as step one.
