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?
Regards
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, 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.

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