MOSFET Amplifier IRFP240/IRFP9240

[apexaudio]

Output seems like mosfet IRf 240 and 9240.

mile is it new ciruit ? seems like all new componets

HV23 is circuit from post #1.

Apex, i back !!!! haha... sory... finaly I can modificate the pictures of my HV350, gooood sound !!!

Nice work, what is rail voltage, bias, speakers...?
Regards

 

[Valenca]

The rail voltage is +/- 80v, I'm not remamber the bias now, speakers I use 4 WPU1509 (450W RMS - Selenium) is a BOOOOOMMMM... but sub-used with this amplifier. Do you undestand me ?

Maximum rail voltage +/-80v is for 4xIRFP240/9240, with 2xIRFP240/9240 use +/-60v max. Do you increase volume to light clip LED?

[Valenca]

No no, 2 x IRFP240/9240 was only for test...

 

[Valenca]

I put those modules in the box with good sink, tell me one thing when the clip LED lights, I mean the the sound is bad?

No clip LED light in case output voltage is 12v to rail voltage, amp clip about 5v output to rail.

hi miles,
can you post power amplifier with grounded collector which you have tested already, coz this amp is simple in design like the PHONIC MAR Series.

Phonic, Behringer... and many other brands are QSC clones.

Apex, do you know the "Times One RF802" power amplifier ? Is a big amplifier !!!!

No, do you have schematic?

 

[wattaniya]

which is best performance hv23 or hv350/hv25

Same performance only BIAS circuit different.

 

[Valenca]

Times one RF802 - Advanced 2500W RMS 2R

Apex, look this!

Thanks for the schematics, but 10 pairs of outputs no thanks

 

[Valenca]

Apex, What's wrong with the 10 pairs? The price of the project? The important thing is that the amplifier is very strong with quality right?

I prefer class H for powerfull amps. For 2500W use 10 pairs and triple class H step driver, like in my VERTEX amp.

can you send class H VERTEX amp with 2500W per channel ?

Here you can find some schematics (CA18, Pro 10001...) of good brand powerfull amps, and build clone.
