Well, That's Something To Find Out, But This Components Show Very Good Specifications Don't You Think?
And Here Are MOSFET's For Audio Applications:
Power Amplification - ALFET Lateral MOSFETs
Applications:
• Professional Audio Amplifiers
• Home Cinema
• Active Speakers and subwoofers
• Instrument amplifiers
• High power car audio
Advantages:
Specifically designed for audio power amplifier output stage applications, ALFET Mosfets are an exclusive new range of devices with outstanding performance and a minimal footprint. They offer superb sonic characteristics and with the features listed below its not hard to see how we can help you to reduce size, cut costs and add real quality and functionality to your design.

• A wide safe operating area (SOA) and absence of secondary breakdown
• Reliable and robust performance when compared to bipolar solutions
• Simplified protection saving cost & reducing complexity
• Improvement of amplifier performance with awkward loads
• Oscillation-free operation on double-die devices
ALFET Mosfets also have a negative temperature coefficient and completely thermally stable bias point without the need for emitter resistors, as used in bipolar amplifiers.

Advanced technical features include:
• Simplified drive circuitry requirements through high
impedance gate
• Inherent output anti-parallel diodes
• Excellent thermal characteristics
• Single live heatsink capability (source connected case)
• Very high bandwidth and slew rate
• No high frequency cross conduction
• Easy paralleling (devices available in selected categories to enhance paralleling performance)
• Soft clipping performance
Application Note
• Lateral MOSFET Design recommendations for Audio Amplifiers

Here I go Again With all you learned people's advice in same leach circuit with some changes and 15024-25 I have reached my goal of 70 volts and much more pressure. Here is snap of a new circuit I designed on multisim 11 . See the specifications with 24 pairs 15024-25 2 pair drivers and 120-0-120 rails

[Tony]

goodluck on your build....

I already have this primary wound traffo and collection of trannies for my project.I only try the things when I have resources .Primary is with 8 s.w.g. A coat of vectol varnish . Insulatig cotton tape and then secondry to my needs. an traffo is ready. for supply.you can imagine power by size.

[AudioSan]

what the he.... 11-12" trafo? whats your plan? start up a power plant?
