Aikido Line-Stage Amplifiers

Aikido Line-Stage Amplifiers
The Aikido amplifier delivers the sonic goods. It offers low distortion, low output impedance, a great PSRR figure, and feedback-free amplification. The secret to its superb performance—despite not using global feedback—lies in its internal symmetry, which balances imperfections with imperfections. As a result, the Aikido circuit works at least a magnitude better than the equivalent grounded-cathode amplifier.

Aikido Noval Stereo
Aikido Noval Stereo
This is a minor new revision of the old Aikido stereo noval PCB, Rev. F. The PCB color is now red, but the real difference is found in two major changes: each channel's B+ RC filter is made up of pure polypropylene (no electrolytic) capacitance and each channel requires its own separate heater power supply.

Aikido 12Vac
Aikido 12Vac
Introducing the new Aikido 12Vac PCB and part kits. The key advantage of the Aikido 12Vac is that it can be operated from a lowly wallwart power supply, yet develop a fairly high-voltage B+ for the triodes.
