Apex sir
Same thread your post #327 & 328 can I use this PSU circuit and pcb with 35-0-35 400VA transformer.Or suggest simple PSU circuit and pcb layout for your AX-14 amp.
I want to build your 100W ultimate fidelity amp AX-14
can you provide correct circuit diagram and PCB layout with bill of material of AX-14. How many watt I can get in 8ohm load with 35-0-35 AC 400VA transformer.
I can't seem to find the A3 schematic anywhere. I've looked in both directory threads and this thread. Must have missed it.
Just added to second directory.

AX11 Bimo mod now up and running in stereo. Mono sound clips posted on Virtual Audition thread.

Still listening to it and will give impressions later after more time. So far so good.

looks cool. what wattage are those emitter resistors? 1W?, better use atleast 3W. I think pcb has option of fitting 5W wirewounds vertically or 5-W 5mm pitch resistor.

I am playing pretty loud right now and those emitter resistors are not even warm. So I think it's OK. I have 5W 0.22R rectangular cement ones but was saving them for another project. The big 2W Zobel resistor is warmer.
Listening impressions:
Very clean neutral amp with wide soundstage and excellent spatial imaging. Low distortion clear highs, no sibillance or fatigue. Great all around amp for listening to wide range of music. Bass is quite good - crisp and punchy. Vocals are excellent and very articulate.
Highly recommended amp to build.

fx 8 is quite expensive to build it, but i heard people said it really has good sound. if ax11 is just the fx8, in my opinion ax 11 its really good too. thanks for your comment sir still4given
Build FH9 if you think FX8 is expensive. FH9 uses less expensive vertical hexFETs. Sounds very good.
You can listen to the difference between an FX8, FH9, and AX11 here.

What do you call expensive? I doubt there is $5 difference between the three different models. FX8 has the fewest parts. I would bet in a blind A/B test you could not tell them apart.

the tiniest board is sonal FX-8 50x50mm, also Dobrivoje with ALF08NP- it has lower price likewise 2x LatMos.
I listen to mine nearly the last month- i like the very clear vocals and the over all easy to
listen- and if you give a bit more juice to speaker you will be surprised.
Also many AX11 around here with different Output Transistors- TO-3 or BD249/250....so
on.
