Introduction:

New STUDER 900 Golden Sealed Transistor Regulated Linear Power Supply is designed with reference to various sources. The power supply is based on op amp servo, using gold sealed transistors as adjustment tubes. When starting, the voltage is steadily increased to the set voltage value and then stabilized. Effectively prevent voltage shock at the moment of startup. The circuit load current is not large, and the maximum continuous peak current of the actual load test does not exceed 2.5A. The noise is very low, reaching the uV level, which is a numerical level lower than that of the LM series voltage regulator circuit. Actually listening to the music is very good sound, and the analog taste is strong.

 

Use 1N5402 high current rectifier diode, The main filter adopts IC 4700uF/35V X4 PCS, and the output capacitor adopts a larger capacitor 470uF to ensure more stable output current. Gold-sealed transistor 2N6688 is used as voltage regulator.

 

It is suitable for the power supply of HIFI preamplifiers, headphone amplifiers, digital players, DAC decoders, instrumentation and other equipment with various low-power loads.

NOTE:The 2N6688 gold-sealed triode is the original disassembled old tube, because there is no new tube in the market now.

 

Inputvoltage: AC 7V --- 24V (According to different DC output voltages, it is decided to use the corresponding AC input voltage).

 

PCB Size: 146mm*110mm

 

Output voltage: We have the following commonly used voltage/current (Optional)

 

◆ DC 5V --- 3A (MAX)
