Default Question about 2*xV Transformers

Hello.
I need one transformer with 9-0-9V and my question is if I can use any 2x9V transformer joint the 0V wire for CT, or isn´t possible always.
Thank you very much.
Jose

Yes. You can always turn a 2 x xV pair of secondaries into a x-0-xV tapped secondary. Just make sure you connect the right ends together. The simplest way to check this is to measure the AC voltage across the ends to see if it is 2xV.

and while experimenting with connections always feed the mains supply through a bulb tester. Sometimes the colour codes are wrong !!

Thanks to both for the reply. I´ll buy the transformer then.
Good advice Andrew, we had too many fires this summer.
Best regards

There was everything. The year was extremely dry, some were neglet, cigars, stubble burning, angry people with management and the euphoria of some pyromaniacal. Them go crazy when planes and helicopters fire going from one island to another desperate.
A unhappy scene.
Sorry a lot for my bad English, I hope you undarstand me.
Best regards
