Sorry Merlin, but personally I would not trust that either. A split bobbin mains transformer will have been hi-pot tested, but primaries to laminations and primaries to secondary. On the transformers that I have to hand, the two primaries generally share the same bobbin and the insulation between them will be to a lower standard. Older transformers will simply have the windings layered and quite likely with less insulation between the two primaries than between them and the secondary windings.
I'm not saying don't do it your way, but I am saying that I wouldn't for the reasons already given.
I made the power supply using the transformer- got 128V and a buzzing from the bee with the microphone. I used a total of 1,440u in capacitors...will a choke help?
It might do, but your volatage will drop back to about 90V if you do a choke input power supply.

I see that the brown wires (recommended output wires) are coming from two separate windings.
The red wires (connected with a capacitor as recommended) are coming from the same winding.
If I can use the red wires rather than the brown...will they be quieter as they are from the same winding?
The red are putting out 168V without load.
The brown put out 60v - 118V without load depending on the capacitor connected to the red.
I wired it as recommended...but if its safe I'll do it a better way.
Is this even a good tranformer to use? (please see picture in previous posts)
