Permalloy 10K: 90K Wideband Passive Preamp 3x Amplifier Three-way Select Input Volume Control | Обустройство дома

Permalloy 10K: 90K wideband passive passive front stage, 3 times magnification, three-way selection input, Nissan ALPS blue shell potentiometer volume control.    Wide frequency response 10K than 90K permalloy signal transformer assembly. Wide-band response slope Mo alloy 10K: 90K triple boost audio transformer, frequency response: 20Hz ~ 76KHz -0.8DB. Can pass 20mA AC signal. There is a three-fold boost and "amplification" of the signal voltage. It can make up for the low volume and low volume of the audio source signal output on the existing market. Features: This unit can be used after CD, decoding and other audio sources, and also after active preamplification. It can be used with either transistor preamp or tube preamp.     Local highlights: Full-featured conversion. The input and output single-ended signals do not need to be plugged in, and they can be completely and completely switched by turning the selection switch. The conversion transformer is a high-precision converter with good matching performance, and the effect is immediate.      Almost all high-end microphones such as Shure, SENNHEISER, Sennheiser, and NIUMAN Newman use permalloy step-up transformers. The output level of the LP vinyl dynamic coil cartridge is only 0.1mv to 0.5mv, and a Permallo step-up transformer is used. The magnetic recording and playback head of the open tape drive uses a Permallo transformer. The US God of War Jensen audio transformer, the Swedish LUNDAH Lunda audio transformer, the British GARDNERS audio transformer, the Japanese TAM Tiemulan audio signal transformer, etc. use Permalloy material almost completely, because the initial permeability of Permalloy is only a few tenth It can work under volts, with extremely high initial permeability and extremely low iron loss. It is ideal for the coupling and transmission of small signals and has a small volume and high permeability. Therefore, Permalloy is the first choice for audio signal transformation.      It is made of German-made Permalloy material with a nickel content of 85%. It is EI35 laminated with a thickness of 25mm. It is fixed with a riding clip.   US US CMC 816 RCA 24K gold signal socket, tight connection and resistance to plugging is not bad

The signal wire inside the machine is selected from the original German LEONI high-purity copper wire, mixed with colorful twisted
