THE REAL 211SE old

The Real 211SE Stereo Power Amplifier

Audio Experience THE REAL 211SE is a SE 25W x 2 Stereo Valve Tube Power Amplifier.

The power amplifier use one 211 power tubes work at SET Single Ended Triode configuration status to provide 25W adequate output . Moreover, It use the high quality output transformer ( Hasimoto . made in Japan).

The input stage is 5687WB tube use Mundorf Mcap EVO SilverGoldOil coupling cap to 5687WB driver tube, The driver tube use Cardas coupling cap to 6189A cathode follow driver stage, The cathode follow stage is direct coupling to 211 tube work at SET Single Ended Triode mode to driver Hasimoto special grade high quality output transformer , The Hasimoto CUT CORE orient high B output transformer has very low Insertion Loss 0.3dB only. ( Many SET tube power amplifier in Hi-End audio market , Their have the output transformers is over 2dB 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 two separately HVB+ power supply for power output stage and input driver stage:
One Hasimoto power transformer with Hasimoto C-core choke and 4 pcs GZ34 rectifier tubes for power output stage..
Other One Hasimoto power transformer for input and driver stage

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.
