    Already do that, nothing happens with 12v power bank, let me try using battery's, i dont know if this can use 18v, but all my electrolict caps is 16v
    I see... that's why I burn twice my barracuda with laptop adaptor and CPU power supply.

      Check voltages at opamps.
      Especially check if you have "-5v" (actually should be -6.22V) on minus pins (pin 4.) at opamps.

        ...your transistors near voltage regulator looks like wrong orientated, or only one. Check pinout, collector from both transistor must be connected togheter, check schematic again.
        Same thing with TX stage transistors.
        From what i see in this picture, FET's are good orientated. Also, check pinout for mpsa13 in audio stage.

          Ivconic sir, for now pin
          1. 0.9v
          2. 2.3
          3. 0
          4. 0.9
          5. 0
          6. 8
          7. 2.6
          8. 0.9
          Using 4xAAA = 11.3v remaining

          Yes CDI, from the schematic its wrong
          Because this schematic

          Have some different with the pcb

          Let me change 2n2222 like the schematic.
          For MPSA13 im sure its on the right direction according to pcb layout and emiter from schematic.

            Oh mannnn!
            What the hell are you doing here?
            Look again page no 1 of this topic and post no 1 on that page.
            You have there zip file with all relevant files for this topic.
            You should NOT pay attention on other stuff posted somewhere else.
            You asked for that project and i gave you that project. Obey it.
            Otherwise don't ask questions which are not directly related to this particular project.
            And wtf are those voltages?!
            Can't you measure voltages ONLY on pins.4 on all DIL8 opamps that you used there?
            So ONLY pin. 4 (minus voltage).
            Take voltmeter; black probe attach to battery minus pole and red probe to pin 4. on opamps, one by one opamp.
            And check what voltage you are having there.
            If that voltage is not in range -6 to -6.22V than charge pump is not working.

              I follow all parts acording to pcb pic, not the schematic
              Pin 4 is 0.9 from two UA741(LM308 subtitute)
              ...I dont know what is charge pump

                If u dont have right schematic for 1265 version i can give u later, cant atm cause in not near my pc.

                  Haaa! Success, CDI was right, 2n2222 is reversed...
                  now coiling....

                    Its already fix CDI, yes thanks, i like the the one package file if not troublesome,
                    Trying to nulling the first time.

                      This is schematic with mpsa13 audio transistor.

                      Also, this is my TGSL build:

                        I dont wish u to be disapointed, but, nulling and fixing the coil is much harder than soldering pcb components. Good luck.

                          Looks factory built to me, is your coil housing a home made? I try to make one and fail til now, no faccum work, just resin.
                          Is there a way to nulling with analog multimeter

                            Not factory made, but my personal work. Coil housing are directly from Bularia, u can find them on ebay, panel screen is also my creation mixed from several pictures from net, maked in adobe photoshop. I dont know for analog, if u have ac range in milivolt, why not.

                                Let me buy one first ...
                                Btw should I change all electrolict caps to 25v? So i can use 18v battery
