BEZ ZAMJENA

300MB is a 7W Valve Tube MONO Power Amplifier.
The power amplifier use one 300B power tubes work at SET Single Ended Triode configuration
status to provide 7W adequate output . Moreover, It use the high quality output transformer (
TANGO . made in Japan).
The input stage use one 5687WB input/ Driver tubes . 5687WB driver tube use Sonicap
coupling capacitor to 300B power tube . The 300B tube work at SET Single Ended Triode mode
to driver TANGO U-808 high quality output transformer , The TANGO U808 output transformer has
very low Insertion Loss 0.5dB 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.
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.
