  1. Hy I ordered from tI TLE2141 and now i replace the integrates. I also replace the 2n2219 with Tip31. now what resistor i must replace? Thank you
  2. Thank you very much audioguru The problem was Q1 and Q3. I switch the Q3 with Q1. In my circuit Q3 was a npn and Q1 a pnp... I will change the tl081 with TLE2141, but for now it's ok with tl.
  3. hello I made the original power supply(30V 0-3A) with all the original parts.( http://electronics-lab.com/projects/power/001/index.html ) I have the maximum output of 11.5V!!! and the led is always on. The voltage after the bridge is 33V dc. I measured the reference ( pin6 to pin4 at U1) and I have 10.6V (I disconnected the P2 and P1).After this i disconnected the D9 and I measured the voltage at pin 6(u2) and is 0 to 11.5V depends of P1. All this measurements was made without load. Please help me
