Symmetric Power Supply circuit per channel 5 amps powering a total of 10 amps voltage control LM317 (negative – at the LM337) is done with LM317 1 amp works fine but the output BD911 BD912 transistors with a strengthened 5 amps made to give filter capacitor, diode bridge and the main circuit all in one pcb on 5Amp Voltage Adjustable Symmetrical Power Supply circuit

Triac Dimmer Circuit 10kW BT139
10kW 6 BT139 TRIAC dimmer circuit by connecting the power line were raised cardiac dimmer circuit (BR100) triggered 1Mohm can be adjusted by a potentiometer. Triac for cooling medium size fin coolers and 12v dc fan was used in practice cooler box contact to the absence of a triac in the installation of isolator was used half deficit to be used or cooling any part in contact with where they do isolators should be used
Triac Dimmer circuit
I noticed that R1 is connected to the output of the regulator as is normal but in this case I would have thought that it should be connected to R13 at the output giving better performance/ stability as it controls the output, taking into consideration the voltage drop across the two emitter junctions and the variable load conditions .
Dear Sir,
I im trying to make this circuit and downloades the file , however it is password protected and I can noo find the password. Do you still have it ?? Can you share ??
Many tahnks
