The Real-X  EL156 Power Amplifier  

Super Flagship Series

Audio Experience THE REAL-X EL156 Mono Block Power Amplifier is a Class AB 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 Telefunken EL156 power tubes and Class AB PP working status to provide 150W adequate output for most of the Hi-End Speakers to ideal performance. Moreover, the high quality output transformer combines with high performance Class AB 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. 

The new design input stage is ECC82  direct coupling to ECC82 driver stage. Telefunken EL156 at Class P-P mode to driver Hashimoto H-156 special grade CUT CORE orient high B output transformer , The Hasimoto special grade CUT CORE orient high B output transformer has very low Insertion Loss 0.15dB 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 power supply with three separately HVB+ power supply for power output stage , power tube G2 and  input driver stage.
The three power supply separately with Hasimoto choke.

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