In order to give some sort of suggestions the Voltage of the transformer is needed. From this the output can be calculated and the number of pairs decided on.

i m going to made transformer at order in dual supply (50.0.50 50.0.50)
i intend use D1047 and B817 pnp npn (8) pairs round about (coz just these transistors are available in my loacal area market)
infect my aim is only that when amp is in high load position and transistors are going to warm at high level. i wanna transformer or amp does not lose his A
just only this purpose i wanna use 30A transformer.nothing else more
now tell me is it would be batter??? or not .if u wanna more detail i will also provide u no problem
waiting ur unique suggestion

50-0-50 at 30 amps? - I take it 15 amp per winding.
Sounds like a might beast, what VA are you proposing?

there is enough voltage there for a powerful amp, the number of output devices needed depends on what the impedance of the load is, a 2 ohm load requires more then an 8 ohm load. and if you intend a Class A, AB or B amp of something more esoteric.

Pick a design, there are many on DIYAudio and see what is suggested

Boot,
go back to the beginning and tell us the brief you are using for this project.
We can then help you come up with a specification to meet that brief.

Once we have a specification we can try to help you choose components that give you a chance of building something that performs close to specification.

There is absolutely no point in going to the end to select a component when we don't know what you need!!!!!
