hi andrew and black thanks for the quick reply . does any one have the pcb files for the higher voltage version on post #99 , #103

+ - 55v and + - 110 vcc

Hi Stewin
greetings H900 apex audio is best to build for + _ 55 and 110 vcc you can use higher power trs for more power its a tested design
warm regards

the my amps 1500w/4 ohms + - 70vcc and + - 140vcc

 

[khalsa]

nice layout your power amp

 

[stewin]

the my amps 1500w/4 ohms + - 70vcc and + - 140vcc

thanks for reply . what are the distortion tests ? and what are the heat levels when drivng 4 ohms?

 

[black]

below 0.05 percent and radiator temperature by Bias adjusted scheme is very good and very stable I'll go forged two years and now very well without any intervention

 

[stewin]

hi black pls post pcb files and schema .
thanking you in advance steve.

Where did you get the Copper Rails? Thanks

Electrical wholesalers. They are called "busses" and are used in electrical switchboards for the mains electrical supply to houses. They come with standardised spacing so make sure you have the specs before you design anything using them.

[wattaniya]

wattaniya no problem in this amp

did u used for outdoor?
what dc v u used?

 

[khalsa]

I use 55 + -,110 + - voltages

 

[sandeep kayarkar]

I use 55 + -,110 + - voltages

50+- 100+-

 

[wattaniya]

I use 55 + -,110 + - voltages

to get 1200w into 4 ohm 120v dc need.

 

[khalsa]

I know but i have this source no problem i made 1 year ago no problem
