The TDA1011 is a monolithic integrated audio amplifier circuit in a 9-lead single in-line (SIL) plastic package. The device
is especially designed for portable radio and recorder applications and delivers up to 4 W in a 4 W load impedance. The
device can deliver up to 6 W into 4 W at 16 V loaded supply in mains-fed applications. The maximum permissible supply
voltage of 24 V makes this circuit very suitable for d.c. and a.c. apparatus, while the very low applicable supply voltage
of 3,6 V permits 6 V applications.

TDA2050 Stereo Audio Power Amplifier
This is 2x30W audio amplifier based on TDA2050 and LM1875. Amplifier PCB is suitable for both TDA2050 and LM1875 chips. Amplifier has all the necessary circuitry on board – power supply, speaker protection, delayed turn-on and fast turn-off. This is achieved using the convenient uPC1237 IC. TDA2050 and LM1875 are pin to pin compatible, the differences in their schematics are the values of a couple resistors and one capacitor. All this allows to make an universal circuit board, suitable for any of these two ICs.
TDA7294 Amplifier
The TDA7294 amplifier module is a monolithic integrated circuit. It is intended for use as an audio class AB amplifier in hi-fi applications. It has a wide voltage range and output current capability, enabling it to supply the highest power into both 4 ohm and 8n ohm loads. With the addition of a handful of parts and a suitable power supply, this module will deliver 50W RMS into 8-ohm with 0.1% THD.
Tube Amplifier Kit
The amplifier kit uses two 11MS8 tubes per channel. The two DC blocking capacitors and the four coupling capacitors are metallized polyester, while Samsung aluminum electrolytic capacitors are used to filter the solid-state power supply.
