The assumption of this project was to create a simple and reliable device. The construction is based on two tubes – 6N2P and 6N13S. The amplifier is divided, what provides good and 'clear' sound.
Power supply:
Power supply uses transformer Zatra TS-40/29/676 with replaced glow winding. The whole construction except the transformer, is mounted on ironed and etched PCB designed in Eagle. Anode supply is filtered by 4 capacitors 220uF/400V. Both voltages (glow and anode) are fed to the amplifier through 'link' made of shielded cable 2x2x0,75 (two twisted pairs). Main socket is also filtered.
Amplifier:
The amplifier was mounted in a classic style ('spider'). That provides convenience and reliability of connections. Final transformers are Zatra TG-2,5-1-66, headphones connected with the correct outputs.
