	Inverting amplifier on the TDA7294 – TDA7293 chip with T-shaped negative feedback. A very good amplifier. The maximum sound quality is obtained from the chip. Excellent board layout, good parts interchangeability. Standard board. Description and documentation: Hi-Fi усилитель на микросхеме TDA7294 / TDA7293	300 руб.
	Inverting amplifier on the TDA7294 – TDA7293 chip with T-shaped negative feedback. The small board contains SMD components. Description and documentation: Малогабаритный Hi-Fi усилитель на микросхеме TDA7294.	260 руб.
	The amplifier on the TDA7294 – TDA7293 chip with adjustable output impedance. Description and documentation: Hi-Fi усилитель с регулируемым выходным сопротивлением на микросхеме TDA7294 / TDA7293	270 руб.
	Amplifier with MOSFET transistors in the output stage. A very simple, yet good amplifier up to 120 W. It has a small increased output impedance (easily adjustable), so it can be used for subwoofer. Description and documentation: Mosfet-Amp: Усилитель с полевыми транзисторами на выходе	470 руб.
	Soft-start for power amplifier. Description and documentation: Softstart – Софтстарт для усилителя	360 руб.
	Class A headphone amplifier with a single-cycle output. It has excellent parameters and great sound. Description and documentation: Усилитель наушников в классе А с однотактным выходом	380 руб.
	Stereo active crossover. The main purpose is to implement bi-amping. The crossover is based on a 3rd order Butterworth filter. It divides the signal into low frequency and high frequency bands. Using film capacitors for the best sound. Good power filter, earth loops are prevented. SMD components are used. Description and documentation: Кроссовер для биампинга	280 руб.
	Subwoofer preamplifier with Linkwitz corrector (which can easily be switched off if you don’t need it). Contains all the necessary elements to control the signal for the subwoofer – volume control, adjustable filter, phase control. Minimal parts, use of film capacitors for good sound. Description and documentation: Предварительный усилитель для сабвуфера с корректором Линквица	430 руб.
	Clip-detector for amplifiers on the TDA7293 chip. When even a small clipping occurs, the LED lights up. It allows several amplifiers to be connected simultaneously for common indication.. Description and documentation: Клип-детектор для TDA7293.	170 руб.
	A printed circuit board for the power supply of a power amplifier. Four 30 mm diameter storage capacitors are installed. Dimensions 90х65 мм Description and documentation	310 руб.
	A printed circuit board for the power supply of a power amplifier. Four 35 mm diameter storage capacitors are installed. Dimensions 105х75 мм Description and documentation	350 руб.
	A printed circuit board for the power supply of a power amplifier. Six 30 mm diameter storage capacitors are installed. Dimensions 125х65 мм Description and documentation	360 руб.
	A printed circuit board for the power supply of a power amplifier. Six 35 mm diameter storage capacitors are installed. Dimensions 140х75 мм Description and documentation	380 руб.
