Notes

Hybrid solid state / tube (valve) amplifier, using tubes for the front end amplification, and solid state for the power output.

  • Terminals for 2 speakers , impedance 4 - 16 ohms
  • CD and DVD input (RCA)
  • Input sensitivity:  300 mV
  • S/N ratio: > 80 dB 
  • THD: < 0.5%
  • Output: 2 x 25 W RMS

Note: the tube heaters are fed with 19 Vpeak half-wave sine waves, approximating 8.5 VRMS. Without modification to the heater ciruit, tubes will have a significantly shorter life.

The product was initially advertised as a "valve amplifier", but later marketed as a hybrid unit, with a reduced price of $99.

Made in China.
