Hi.
I was just wondering, when soldering the grounds to the transformers, to make it clean , I have twisted the three cables going from the ground screw and used shrink tubing, letting one by one leave the twist as the ground buss passed Ot(c) , PT, an finally one left for OT(a). Sounds ok?
And the wiring of the PT5, is it ok to solder the drain wire to the ground screw instead of the E of the IEC?
