Tim__x,
For Your information, designer is, regarding his education and experience, in same league with Pass and Leach. And we really need to appreciate his participation on this DIY forum.

Unfortunately, this forum is flooded with smart members not willing to offer solutions for DIY community. They just offer never-ending critics.

Head Spaz: I was referring to the amp directly above my post.

As for being a never-ending critic not willing to offer solutions, I don't think that's quite fair. It is in some cases true, but I try to helpful when I can. Here I've suggested splitting the two CCSes giving them separate references. And removing the resistor I mentioned, you'll note that the collector of the LTP transistor on the left hand side sees a rather low impedance, what with the 1.5nf cap and the VAS loading it, so this resistor actually hurts symmetry rather than improving it.

Edit: I switched left and right before.

Hi Tim__x,

Sorry for misinterpretation.
In the post #21, only first part is related to you. Second part is like general conclusion nothing to do with you.

Best Regards

No doubt, this is not a perfect amp. Like with any other schematic, it is possible to improve design.
This schematics and PCB are proven in real life. Amplifier is easy to build, not expensive, reliable and the most important - good sounding.
If it is good enough for professional Tannoy-Monitors (for recording studios), than it is more than sufficient for most of the home systems.

Amp specs:
> Output Power --------- 85W RMS/8 ohm
> THD ------------------- 0.003% (20Hz-16KHz)... 0.008% @ 20KHz
> TIM ------------------- 0.002%
> Slew rate ------------- 50V/uS
> Damping factor ------- >650

Default Bob03,

I second your opinion regarding the performance of Studio amp by Bora.
Pls refer to the link(http://www.diyaudio.com/forums/showt...437#post807437) post #78


Cheers.

Huh? I just asked On when I could expect mine, and they said they're out of them and there's a seven week wait!

XEaglekeeper, how did you order them? From the Onsemi site?

The exact part number is "MJL4302AG"?

Thanks.

Reid
