1000W Simple PA Amplifier

[apexaudio]

Can we use different parts like 15023 at output. 0281-0302 are hard to find Sir.

TIP35C/36C can be use for step and MJW21195/21196 for outputs.

BA2000....Looks like Proline T-Amp.

Many brands use this simple realable circuit for high power PA amplifiers.

hi apex audio i want soft start circuit pcb layout file which i didn't find. you are doing a great job.love you.

I share many soft-start circuits.

hi apex audio what is wattage of this soft start circuit .where is relay?

 

[andrewlebon]

itsTriac based soft start circuit

 

[rohin]

ok, can i use this soft start circuit for 1 kw amplifier ?

Why did you avoid the rail switching?

I have some 2x90vac transformers and B2000 was made only for use them, but with series connect of outputs TIP35C/36C can be use with +/-90V rail or MJ15003/15004 with +/-120V...

I guess, that transformers are huge... This amp need about 3kVA...

Transformers are for 4U case.

Transformers are for 4U case.

That will be nice project.

I think the class TD would be better for that high voltage.
