Dinesh, not yet. I would like to. Seems they rock.
They really do actually, I built mine a number of months ago, it has really clean power. I find that there isn't anything particularly special about the circuit but because it is kept simple there isn't a whole lot of colouration to the sound.
I managed to fit the amp into a 12x8x2 aluminum enclosure from Hammond with a 300VA 30Vac x 2 toroid transformer. This result in 42-43 volt supply rails, the bias is set for 60 or 75Ma, I can't remember exactly and the output transistors are mounted to the aluminum chassis. When pushing the amp without a fan blowing over the case it gets in the range of 70 degrees C, pretty darn hot.
I think the biggest improvement I made over what the original design calls for is with the power supply, there are two bridge rectifiers, one for each rail, each diode snubbed with a 10nF-0.1MFD cap. 4x10,000MFD and 2x6800MFD(Elna Cerifine), all wired with solid 14awg copper.... all this is a bit overkill but the end result is very good.
I have built this P3A amp and it sounded so good. The vocals is so clear. The cymbals is so transparent and detailed. The bass is thunderous. Simplicity in design but superior in sonics.
excellent description of the sound
I have had such good results with how I built the amplifier I feel that I should provide the wiring for the clad board I used, it is a perfectly symmetrical layout and so far works excellent in terms of sound.
I think what impresses me most is how easy it is to throw in various transistors without much trouble.... I have all used parts and are different from the ones specified. Outputs are Sanken 2SC2773/2SA1169, Drivers are Toshiba 2SC2238/2SA968, the LTP, is a 2SC3381 and the LED CCS(if I am not mistaken) for the LTP uses a 2SC2240.
Just I some ideas to and success to throw out there as this is the first SS power amp I ever built and I love every bit about it, and right now I am in the process of a JLH SS preamp. Next on my platter for a future build is a dual mono JLH power amp to go with the preamp I am building.
