Default Power supply el84se hook up

HEllo, I finally have time to build a el84se from below schematic.
My question is: how do I hook up the transformer on the sec. side?
I figuered out the paralleling of the two sec. 230V... :-)
So, how do I put the two together for the caps etc of the further on power supply?
Greetings

No. The two 230V secondaries should be wired in series, with the junction connected to the negative end of the first PSU capacitor.

The two secondaries need to be wired in phase with each other. To check this join them (probably 10-11), then measure the AC voltage across the other ends (9 to 12). You should see around 460V. If it is very low. swap one of them and try again.

If you don't have one, build a lamp limiter before you try to get the PSU going. This will help you avoid bangs and blown fuses when you get something wrong.

Hi, thanks for your answer! Junction of 10 + 11 and measuring 530V at 9 + 12... Good?
9 + 12 will go to the first 50 5W and plus cap... junction out of 9 + 10 will go to first cap minus ... Good?
Didn't need the lamp... :-)

The two OPT diodes are a popular affectation, but will achieve nothing.

More important, don't forget the two PSU diodes!
