ok, Thanks a lot. got myself 2 18000uF caps.. haha by the way, can i change the 0.47ohm 10W resistor with a 0.05ohm 9w instead. reduces the overall power consumed.

hi everyone, its me again. I have a ques, can the 12,000uF, 63V is replaced with a 18,000uF, 50V. i cant find one with 63V. and the other i can find is 8000uF at 50v and 100V. u suggest parallel-ing the 8000uF o use a single 18,000uF 50v? but i feel the 50V would do good enough. i would like to thank for any comment or suggestion. Im cant access the forums the office in PC. so, Thanks again in advance.

Alright. :) Thanks a million. I'm still going over the forum. Thanks again.

Hi all, I have a few question regarding to the modified version PSU. I noticed that the out for U1 is 11.2V and it's operating in fixed configuration. Can a high precision OPA 27 or OPA37 being used instead? another question is regarding to the TIP31 NPN Transistor for Q1 and Q2, a compatible part is BD131 NPN. But can a BD132 PNP be used instead? BD132 is the complementary part of BD131. Thanks in advance.
