Transformer replacement

[Jack// ani]

Can I use 12V, 2amp centre tapped transformer in place of a 24V/2amp. I
will not use the tapped wire, so I'll get 24volts across its two
ends.

TIA

Nope. The center tap provides a voltage tap halfway between the two
legs, like this (view in fixed font or Notepad):
` 12VCT Secondary Transformer

Can't get there (24VAC) from here (12VAC). Whether you use the center
tap or not, you've only got 12VAC. Sorry.

Good luck
