Hi friends,
Recently i bought Jims audio's Symmetric JC-2 kit from ebay. Later i assembled carefully (i am not expert) and plug in power. Amp worked and play music well (without hum). now whats my problem is, when i fixing parts in pcb, i wrongly soldered 2SA1145 (one channel) in wrong direction. but immediately (first time plugin power) i found problem and fixing in the correct direction. but one channel not working. so, i replaced the said trans locally purchased (it may be fake because of its print). Now circuit working but measuring voltage, dc output in psu level is +/- 20.8v. but its dropped to 8.5v (2k trimmers alignment doesn't make any differences) as mentioned in the picture and the left & right corner BD 139,BD140 warm well. Please anybody let me notify the problem.
Thanks in advance
