Cyber 10 Multifuntion Amplifier

Cyber-10 is a single ended Class A tube integrated amplifier,using KT88/6550 or EL34 and KT77  by re-biasing .incorporating a fixed bias design for easy tube swap and more power delivery.  a trim pot for adjustment to get to 0.4mA bias current. The bias adjustment can be measured by a voltmeter . Operating in Ultra linear mode [12W output]or triode mode [6W output].

Also featuring a headphone socket impedance ranging from 10 to 600 ohm. One USB and 3 RCA inputs  with remote volume control.

Cyber 30 2A3 3.5wpe S.E.T. Integrated/power amplifier

Cyber 30                    
Integrated amplifier,single-ended ,3.5wpc, supplied with Sovtek 2A3 triodes,       
TJmesh-plates available on request.

Single-ended class A integrated amplifier.using no global feedback. The 12AX7/ECC83  dual triodes, acts as input and drive tube. The 2A3 is self biased . AC voltage applied to the input goes first to the front panel volume control and then to the 12AX7/ECC83. The 12AX7/ECC83 provides voltage gain and drives the 2A3 output tube. The 2A3 is transformer-coupled to the load.
