The supply receives -20 V from the rectifier/filter which is fed to the collector of the Darlington pnp pass transistor, a TIP105. The base drive to the TIP105 is supplied through resistor R5. The base of the TIP is driven from Vz terminal at pin 9, which is the anode of a 6.2-V zener diode [...]

Friends at don’t like large-sized of a transformer. I begs for to advise 15VDC regulator power supply can give the trend current get low about 80mA not exceed. But enough will usable small-sized circuit has comfortablely. Think I uses Zener Diode be formed help maintain [...]

A friend of me you one take an interest a side Sound Audio the very. He takes an interest to want to build Pre tone Control which use the integrated circuit OP-AMP. By these circuit often use power supply Model Dual DC Regulator which have [...]
