Default Awesome SR-84 EL84 push-pull tube amplifier!!

Hi all, haven't been here with new products for a long time...Now we are proudly announce our new product
SR-84 EL84 push-pull hifi tube amplifier

It took us almost one year to develop this excellent amplifier. The preamp is 12AX7, the power stage is 2 EL84 to form push-pull circuit. Max output power is up to 10W. The circuit board and components are highly optimized for hifi equipment: ROE capacitors, DAL resistors, our best optimus transformer and high-temp silver coated cables.

There're many other features that make it a nice amplifier:
  • 110V/220V compatible
  • Power on delay relay
  • Speaker protect circuit
  • Loudness switch
  • Speaker/Headphone auto swith
  • All CNC aluminum enclosure
  • Transparent top cover

More than 30 have been sold locally during the past 3 weeks, full of good feedbacks.

Price is $1299 but not it's in big discount, only $899. If anyone is willing to test and post review there's another $200 discount! Contact me for this please.

The loudness control switch makes this amplifier very interesting. It improve the signal above 1KHz significantly. The spectrum shows that the signal power at 20KHz is 4dB higer than 1KHz. It was 1dB lower without loudness control circuit. Listen is quite different with the switch on. Personally I feel that the sound with loundness on is much better than without it.
