Hi Sumesh, just increase the restring option in DRC to say 24mils (min and max values) and you will get larger pads.
Attached is the DRU file I use for most layouts. Just save it in eagle's dru folder where eagle is installed and press 'DRC' in layout and press 'load' and select the saved file. You are good to go.

Hello sir,
Here is the modified layout. Wow! that's a lot of traces for such a small circuit (enough spaghetti for my lunch and dinner).
Anyway, how does the design fare now? each and every ground point runs to the star. I will keep on doing small modifications for DRC compliance

Mr. Miles,
changed to 2k2 resistor (R3/R8)for increasing the gain .
Ivanlukic has built the above design and he has posted his impressions in this thread here.

Since the circuit was posted here by Mr. Mile here, just thought to let everyone know here.

Hi sir Mile i have a problem with my apex F100 power suply. when the volume from my pc is 70 procent she is gone to protection and when i put down the volume the protect is return. Can you help my about that problem. I use 1k resistor 5w and 1k2 resistor 3w . I dont have 1k2 5w and the problem persist. The amplifier is not in cliping! trafo what i use is 2x42ac. 650w.
An externally hosted image should be here but it was not working when we last tested it.

I use resistors in the RCL library, for example R-EU_0204/7. The pads on these seem large enough to me.
Dear gannaji,
Yep, I was intending to imply diptrace only. I couldn't remember the name of the software yesterday so I mentioned the name of prolific users of that software {Vzaichecko and JWilhelm.}
To be honest, I never tried to learn any other software seriously, as I think I have good capability with eagle.
I did make a somewhat complicated layout with sprint for a well-known amp designer, but it was merely a copy and some beautification project that was sponsored. It took a week of hard work (6PM-2AM), most of the time was spent in checking the connections and packages. if there was a sch , then I would have done it in eagle, then it would have been a 2-3 days affair.
Since most newbie DIYers and soon-to-be-pcb-designers visit and read this thread, my advice would be to spend some time and learn any schematic capturing software, like Eagle/Diptrace/DesignSpark/Protel. Their DIYA life would be much easier.
regds,
Prasi

Your LME49830 link to a "Batteries-Plus" site in France makes absolutely no sense.

why 3 to-126 devices? i see only 2 to-126 devices on your original sch...with which i made a layout.
if the sch is revised with new devices, pl post here Mr. Mile.
APEX A40
Hi, friends. Tell me please, How much power will the APEX A40 amplifier have at a voltage PSU 65-0-65V ?

That seems very low.
My Leach clone got just over 170W into 8r0 from a dual 40Vac transformer that gave supply rails of +-58.5Vdc.
