To help alleviate some stress on the transformer, redo all of the solder points on it, and their first connections beyond the transformer. I would even redo any connections from the outlet plug, to the transformer. By redoing, I mean desolder the points, clean all solder off and really clean the tabs on the transformer and other points. Then solder wires back on with fresh solder.

Would be a good idea to replace the connectors and header pins, if that’s where the wires leaving the transformer land. Been awhile since I’ve seen the inside of TAF.

What you’re wanting to accomplish, is giving the transformer a clean path to work, coming into it, and out of it. Age, dust/crud, corroded connections, will make it work harder than it should, due to the resistance being caused at those points.

Clean path = happy electronics.

I can’t guarantee this is a 100% fix, but it will help, and ensure it has a clean path to work as it should. A little time consuming, but will give peace of mind after it’s done.

Power can be created, but not destroyed, it has to be repurposed in other ways, for it to dissipate(usually turned into heat). Examples being heatsinks, resistor bodies, ect...some way to eliminate the power it’s not going to use. If an item is getting too hot, something’s clogging up its path, to where it can’t breathe/function.

Think of a water hose, when clogged, doesn’t operate very well. When cleared, it works as it should. Same theory.
