Hi.
This is my first post and I am a bit of an electronics noob.
My project is a 6L6 Clementine SET power amp based on the 1626 Darling. The schematic is on diytube.com • Index page. I've been told the trany needs a bridge rectifier but I don't have a clue as to where I should connect it to let alone the wiring for the filaments or power this transformer. Can anyone please help me with this?
I'm in South Korea where the line voltage is 220v 60Hz.

Welcome.
Clementine design wants a 190VAC (380VCT) transformer.
Your transformer offers 250VAC (or 265VAC).
Your B+ will be 30% too high. Unchanged, the poor 6L6 will run about 70% hotter than designed.
I'm thinking this is too much of a change for a "noob" to manage, if those winding tabs are not already making sense. (I agree I go a bit cross-eye looking at them.)
The answer is "0V and 250V", but this is too much for this plan and will not lead to a happy amplifier. The 6L6es, the OTs, and the 350V caps will all be very nearly AT their safe ratings. It could be re-designed, but you are not ready to do that yet.

Awesome!
Thank you so much for the reply.
So looks like a Hammond 369EX should be the correct one for me, right?

That will work. The original schematic specified the 269EX, and the only difference between the two is the primary voltage options. So configure the 369EX primary for 220V, and follow the schematic directly (don't use bridge rectification).
