pt05 diy preamplifier

The next stage is working with the first stage as well it is a fully-complementary. The cascode circuit is also in this place to improve linearity of the amplifiers. Cascode circuit requires a constant reference voltage biasing to make a cascode transistor on. We chose to use a transistor array as a voltage reference. Because it requires less curr

ent compared to the use of zener diode, diode and LED, and of course, it has lower noise. The overall voltage gain is set to 12 times. What are the power supply of my PT05 DIY preamplifier. It is a linear power supply with a voltage regulation circuit includes a rectifier and regulator IC amounting 2 pieces per side. It was called a 2. 1 voltage regulation. 2 is 2 stages voltage regulation by 2 regulator ICs. 0. 1 is a shunt voltage regulator. So I called it a 2. 1 voltage regulation. Overall, It would polite sound. The deep bass is slightly less than the PT03. But it gives the better musical. Midrange and treble detailed are done very well.
