New circuit board! SORRY, SOLD OUT
Product Description
24V Aikido Tube Line Stage and Headphone Amplifier
Custom tailored for the 6GM8/ECC86/6N27P and a 24V power supply. In addition, the PCB fits a class-A, single-ended, unity-gain, solid-state buffer output stage, for driving low-impedance headphones (32 to 600-ohms). Board measures 5in by 10in, with eight mounting holes. Boards are made in the USA and come with schematic and recommended part values and design examples.
What makes them superior? First of all, they look fabulous and feel solid in the hand: extra thick (inserting and pulling tubes from their sockets won’t bend or break this board), double-sided, with 2oz copper traces, clean silkscreen and solder mask. (The board holds two sets of differently spaced solder pads for each critical resistor, so that radial and axial resistors can be easily used. Many capacitors finds several solder pads, so wildly differing sized coupling capacitors can neatly be placed on the board.) Each board holds two Aikido linestage/headphone amplifiers; so, one board for stereo unbalanced or one board for one channel of balanced amplification.
