Another Symmetric Power Supply Without Center Tapped Transformer

Don’t worry if you need a symmetric power supply and you don’t have a center tapped transformer. The circuit below solve your problem. You can see the second bridge diode is powered via capacitor decoupling, so it’s DC isolated. Because it’s DC isolated, we can connect the ground together to form a symmetric supply. Because the second rectifier is powered […]

Simple Symmetric Power Supply Without Center Tapped Transformer

It seems that center tapped transformer with a bridge diode is common solution to provide symmetric power supply, but we can actually do it with simpler solution, using a voltage doubler – rectifier diodes. You can see this simple circuit in the figure. The capacitor need to be large because the rectifying is half wave, so you can avoid power […]

Ibanez Fat Cat Distortion Pedal

Ibanez Fat Cat distortion pedal (Ibanez FC-10 Fat Cat Distortion) is good for blues, rock, pop, alternative, but not for metal. You can hear the fat tone even at maximum overdrive. Here is the circuit schematic diagram. You can see the the first transistor 2SC1815/BC546 is configured as voltage follower, giving a high impedance for the input. The op-amp (5534 […]
