100W Ultimate Fidelity Amplifier

Hi Willy,
Can you send me the corrected copy including the PCB. I have 2 pairs of MJ15024 & MJ15025.

Thanks.

Hi Rey,

AX amplifiers can work in class H, just add this circuit 🙂

Hi Rey.
If you use this pcb on +/-50V, replace MPSA92 with BF872, BF762 or 472.
Because on that voltage and 200mW dissipation, MPSA92 will be so hot. Or use something like this:

AX11 or Studio Reference series?

Hi Mile,

I was wondering about the difference between your AX11 in this thread and the studio reference series amplifiers. Other than power differences, is there an acoustic advantage of one over the other (in your opinion)?

Could you please also explain what you meant in your post http://www.diyaudio.com/forums/solid-state/173462-studio-reference-amplifier.html#post2313884

Rail voltage for SR200 is +/-75V, I prefer sound of bass from this amplifier topology.

How would you say the bass was better?

Thanks in advance.

Bass is stronger if this is better 🙂

where you connected basis?????

Those are the output transistors of the existing circuit. So, basis connections come from the previous section. Maybe he should have drawn those existing parts using dashed lines.

Thanks for your reply. Do you attribute the stronger bass in the SR200 to the output stage simply having more pairs, or is this due to other differences in the topology?

Hi, Mile!
Do you a have a quasi version of AX-11, with NPN BJT outputs?
Many thanks.

This SR200 topology and AX11 topology have stronger bass.

There is no quasi AX11

This looks interesting small class H amp Mr. Mile.

Will this stay in the same thread?

FYI work in progress...😉 but will continue tommorow as it's getting late now and have to wake up early tommorow for work.

Have a great weekend to all...

I suggest to use single pair of outputs 2SC5200/2SA1943 no need for two pairs, and step transistors can be TO220 like IRF4905/IRF3205 or IRF540/IRF9540.
You have some about simple classH amp H100 in thread:

Noted Mr. Mile...

I have drawn F100 but still not posted on the thread and can revise it into class H soon.
