I want your opinion, about these two amps...
http://sound.westhost.com/project3a.htm (Elliot's)
http://www.ampslab.com/c200.htm (ampslab)
Which one is better, in overall terms ? I'll use it to drive a nice 4 Ohms subwoofer, and in your opinion, which one is better at lower frequences, and are better designed?
I was determined to build the c200, but I found recently this amp at the elliot's site, and it appears to be better in my opinion.
I bought the transistors to build the c200, but they were all fakes
So, now I can choose again which amp I'll build !
c200 is more powerful, but not in my system, cause it will be supplyed with 32+32v only...
Thanks !!

P3a is a good amp, tried and tested. It is also simpler. There is a dedicated ESP forum where you can get help as well.
However the ampslab ones come as a kit so there's no issue sourcing the right parts. However the kit could cost more than you buying the parts yourself, I don't know what's available in your country or what prices are like.

The c200 is not designed for this voltage.
There are no design flaws. Without resorting to servos and trimpots, these "unbalanced" values actually minimise the DC-Offset that is inherent in such topology. Set both at 47K and DC Offset will exceed 100mV.
The c300 is very stable. It will even survive a dead short at the outputs.
I don't have to. I am not in the business of teaching novices how to construct solid state amps.
From EF to CFP to Quasi, build them exactly as in my website and they will work. If they don't, the problem lies in the construction or components, not the circuit. All variations are full working models, not Spice simulations. They were tested with resistive loads first, followed by speakers for a minimum of 2 weeks continuous 24 hours music playback.
I do not put up designs that are "Flawed". That would be fatal for AmpsLab.
