Indeed, sometimes technical details are more important than mind-comfort. haha.
I have, btw, built my PSU in a similar but simpler way — rectifier & cap bank sitting above the tranny, minimum space (a mere few mm so that they're not touching each-other) and nothing in-between. It's quiet.
And pls do not remind me how many times I dissected the PSU or its alignment in the chassis to try to get them into the symmetric axis, or get the shortest possible wires. (OCD, yeah yeah yeah)

Just received my Toroidy transformer. I am a compete newbie here. I've asked a friend, but I'd like to confirm with you guys please. As you can see, secondaries are Red-Red, Brown-Brown.
So does red-red go to one bridge rectifier and brown-brown to the other rectifier?
Also, as this is 230v, UK voltage. Do I have one CL-60 on the live-neutral connector and x1 cap across the two white transformer inputs? I know this should be obvious, but want to double/triple check.
Thanks all for your much appreciated help!

Yes, you are right about red-red and brown-brown.
Capacitor goes between the live and neutral. C60 goes on the live wire from the switch to the transformer. Perhaps pictures will help.

That's brilliant, thank you very much! I always thought the safety capacitor went on the transformer side.. And the CL-60 on the switch side. But I'll follow your pictures, thanks again!

To be sure, notice that CL-60 does not go across the live and neutral (as capacitor does), it goes on the live wire.

The safety capacitor should be placed right after the iec, the masters said (not too long ago). I put it right at the IEC‘s connector-blades...

Ok, thank you.. I'll see if I can fit it there, although I've got this far at the moment..
Does it look ok? First time I've attempted to build a amp after 35 years in the hobby!
