HIFI power amplifier and amplifierHIFI power amplifier is the symbol of high-fidelity power amplifier. The amplifying components of the power amplifier are mainly divided into three categories: electronic tubes (tube amplifiers), transistors, and integrate

A Brief Discussion on Tube AmplifierI have been in contact with tube amplifiers for more than ten years. The first one I bought was the Japanese Lux EL34 tube amplifier. Similar to the original audio, it was also out of interest in technology. From then on,

Cause Analysis of Common Faults of Tube-amplifier Power Amplifiers1. The output power becomes smaller and the sound becomes weak1. Power tube agingThe screen current of the power tube can be measured. Use a 100mA DC ammeter, connect the negative test lead to the screen pole, and

The role of tube amplifiersame speakersDifferent power amplifiers bring different effects!The signal from the audio source is sent to the amplifierA lot has changed in the amp!Power amplifier for high and low impedance conversionThe signal going into

Introduction to amplifier knowledgeTube amplifier refers to the audio amplifier of the electronic tube. Some tubes are used for power amplification, and some are used for polishing or voltage amplification. The tube amplifier has its unique "taste of guts", the sound is warm and durable, the sense o

How to choose tube amplifier?The core of the HiFi power amplifier system is responsible for amplifying the signal received by the CD part, transmitting it to the speaker and then emitting sound.The power amplifier is also divided into pre-stage and po
