So, next step with this is I guess is to bring up the severely damaged radio section.
The TV section has run OK for a while with no major problems and seems to be stable, aside from the slight video smearing / ringing that changes with fine tuning, this I hope to improve with IF alignment.
But, as before, having no sweep marker generator and just a digital RF function generator, I can only do the general MIN/MAX adjustments, and not the overall video IF response check where the response curve is plotted.
But I'm hoping to get SOME improvement with the VOM method, I just wish one did not have to remove the CRT to do it, but there is just no way to get to the coils with it in, it's almost, but not quite impossible take the IF tubes in/out with the CRT in, the spacing is so tight!
As for the Radio, as mentioned, I will be using the very old Sansui P-130 power transformer I have, to replace the burned original, of which I can find no info online, but it seems close to use voltage wise.
I have decided NOT TO wire in the damaged 5u4gb area, I will leave it bypassed, but may wire up the heaters only.
In its place I will use a pair of BYV26E-TR diodes, this obviously will raise the bias a bit, and thus have to raise R160 candohm resistor's replacement (500 ohms) till the bias is in the right range.
