The Real power amplifier

The Real Power Amplifier version 1.5

Audio Experience THE REAL Mono Block Power Amplifier is a Class A PP design power amplifier. It provides sound deep and wide stage, accompanies with reality sound image and a emotions sound presentation.

It uses two matched pair of 300B power tubes and Class A PP working status to provide 34W adequate output for most of the Hi-End Speakers to ideal performance. Moreover, the high quality output transformer combines with high performance Class A PP circuit design lead to an extremely low loss, wide sequence sound effect and excellent phases output. This power amplifier case structure and parts arrangement are perfect, the signal path is directly and shortly connected. Great heat dissipation, an anti-shock and anti-RF function to guarantee it works at a very stable status. For sure, this machine is produced by point-to-point methodology.

Features

The input stage is 12AU7 direct coupling to 5687WB driver stage , The driver stage use high quality capacitors to 300B power tube , The 300B work at Class A P-P mode to driver Hasimoto output transformer , The Hasimoto special grade (HW-60) CUT CORE orient high B output transformer has very low Insertion Loss 0.2dB only. ( Many tube power amplifier in Hi-End audio market , Their have the output transformers is over 1dB Insertion Loss . only about 10% very high price tube amplifier use under 1dB Insertion Loss of output transformer ) . The output transformer has low insertion loss is very important , the best of the best is 0 dB Insertion Loss , The output transformers for High End tube amplifier need under 1dB Insertion Loss . The Insertion Loss over 1.5dB output transformer will lost many low level music.

The components , NFB value , tube type , circuit all select by listen test.

The use highest quality transformers .
