i have 2 transformers—–same type—–15 v 6a —each———made by same manufacturer-- i join the 0 v of each to make dual rail supply of 15-0-15 v 6a --ac--for amplifier

--The turns on a pair of paralleled secondary must be IDENTICAL----i guess they are same as made by same manufacturer-------

cheap transformer rated at 16-0-16 v 6a w.r.t to 2 rails so each rail gets 3a ?

my main intention of making this--------because 2 16 v transformer cheaper than 16-016 v transf---and i will get 6a on each rail ?

now what do you think can it be done without any issues ?

thank you

Is this for a mono set up or stereo?
If stereo, then very simple, use a single transofmer for each amplifier channel.

Mono + you have multiple output transistors, wire output transtors one half onto first transfomer other half output transistor input volage on second transfomer.
Using this method you are immune to voltage diffrences due to transfomer matching.
