Also double check each of the fets for short between Drain and your chassis (make sure the through bolt is insulated).
Thank you guys. right channel one connection loose. I resoldered now fine. Then left channel problem came. Checked and resoldered. When I poweron some small smoke came from left channel board and both channels are playing now.🙂
left channel volatge is around 230mv. Right channel is nearly 0mV. so 230mV dont cause any problem. Special Thanks Zen Mod for making me in the right direction.

hi ragazzo !
i have transformed my stock Aleph3 in ALeph3 J M
Jfet input , no aleph gain resistor (plain CCS mode), no ouptut resistor ,and 1.8A per device (38W)
i have mesure it yesterday with a friend CLIO and got : 0,01% THD at 1W mostly 2order and less than half 3 order distorsions. start clipping at 12W
for the sound low end seems less controlled than it was before with aleph CCS,
but mids and highs are to die for like a very good Tube SET amp

Hi Alex do you want to know which one preamplifier?
Next Saturday i and my fried will try x-ccs bosoz, audio research and kondo (I don't know model).
Hi guy !Yesterday i and my friends turned on the power amp and listened for the first time.
I must say that the first impression was disappointing regarding the dynamics and the extension towards the low range. I hope to be input to the psu that needs a few hours of break-in, otherwise I will have to investigate other possible causes such as the cell L C R on the speaker protector, or genuineness of the 2sj 313.
