Fitted with simple to use bias adjustment.
By simply rotating the control knob on the front of the chassis and selecting between each valve numbered 1-8, the user can adjust the individual biasing using the  panel mounted meter.

The Cyber880 is an extremely potent amplifier with power, superb definition, and great control. Using eight KT88/6550 output tubes and a low-mu octal driver, this amplifier possesses an uncanny ability to reveal every nuance in a recording, while preserve the emotion and feel necessary for a truly musical performance. In addition to finesse, it has great power, impact, control, and a low electrical noise floor. This remarkable overall character makes it suitable for use with speakers ranging from high efficiency to the most difficult and demanding.
The aluminium front panel and top cover are finished in hand rubbed silver metallic lacquer.
 Output matching taps are provided for 4, and 8 ohm speakers.

The Cyber880A uses four 2A3 triodes per channel in push/pull configuration and low-mu drivers, this amplifier has a amazing amount of musical clarity while at the same time possessing enough power to drive most speakers.
 You no longer need to worry if your already existing speakers can be driven by a tube amplifier, this eight tubed 2A3 amp can handle virtually anything.
  In addition to the power it has finesse, impact, control, and a low electrical noise floor. This remarkable overall character makes it suitable for almost any music fan. It contains a solid 30 watts per channel (with low impedance) but with the charm of tubes.
  The aluminum front panel and top cover are finished in hand rubbed silver metalic lacquer, with a bias meter and tube adjustors that make it easy to maintain and adjust. Output matching taps are provided for 4, and 8 ohm speakers.
