AX11 with TO3 outputs.

Output power over 105W/4R (20,78v RMS) with +/-37V DC rail voltage.

many diyers build AX11 last days 🙂

you haven´t told them what happened at +/-50V supply...

210W/4R RMS 🙂 but I don't want more than 100W/4R from AX11.

Wow! That’s powerful little piece of amp….

yes,200W/4R with +/-50V PSU and single pair of MJ21193/94 as output transistors 🙂

the Dude nailed it! 🙂

I use 8ohms speakers.
I would want an AX11 that did 100W into 8r0 and capable of driving reactive 8ohms speaker.

AX11 is amplifier for 50W 8ohms speakers.

my AX-11, nice sound....

Great job!

AX11 is amplifier for 50W 8ohms speakers.

are you also stating that the same AX11 is a 100W into 4ohms capable amplifier?

If you are then it should be able to do 100W into 8ohms if all the devices are suitable for the higher rail voltages required for this 100W duty.

Nice work, can you post beter pictures?

AX11 maximum rail voltage is +/-40V, this not suport 100W into 8R.

That's quite clear.

Is there anything to correct

An externally hosted image should be here but it was not working when we last tested it.

Yes, beter use original PCB

hello sir can i use this,

is any track is missing . . .
