a newbie question, is it possible to combine/parallel two identical transformer to make a voltage/amperes higher?
like 2x 12v/3amp transformer combined to make 24v/6amp:
positive+positive negative+negative.

As long as they are truly identical, then it's acceptable to connect all secondary leads in parallel.
A better way might be to connect each transformer for 12v 6a (by paralleling secondary) and connect these in series. This would also be acceptable for non-identical transformers.
Remember there is no +ve or -ve as we are dealing with AC here. It's phase that matters

No. 2 12v 3a transformers in parallel will be 12v 6a
2 12v 3a in seriese will be 24v 3a
It may be helpful to add the term VA. VA or volt amp is
the amount of power . For a 12v 3a transformer this works
out to 12v x 3a = 36va . So when you add 2 12v 3a transformers
in parelle you get 12v X 6a or 72va 36va from each transformer.
Now if you use a full wave bridge rectifier and 2 capacitors
with 2 seriese connected 12v 3a transformers you can come
up with ~ +15v = and ~ -15v. But the amp rating of the 15v
supplies will be a lot less than 3a.
