I would like to built another SimpleSE.
I have in stock a power transformer the James JS-9611.
Can I use it with the SimpleSE ?
For the 6.3V, I dont have only 2 wires like Hammond.
How should I connect the james to the board ?

You could parallel Secondary 3, 4 and 5 together and connect them to the Simple SE board. That would get you nine amps of 6.3 volts. That might even be too much capacity - you might find the heater voltage tends to run high. If so, just use two of the 6.3 volt secondaries.

Keep the 2.5 volt taps on sec 4 and sec 5 away from anything. Wire nut and / or tape them back safely out of the way.

Be sure to observe the proper phasing of the windings - if you parallel them out of phase, you'll get zero volts instead of 6.3.
