Thanks for supporting the Tube CAD JournalDesign your own Aikido Octal Mono Line-Amplifier Kit. Add to a pair printed mono circuit boards and User Guide only those parts that you need! Select from the following drop-down boxes the parts that you need to populate the stereo PCB.
Product Description
Design your own kit. If you already own many or none of the parts needed in building your own giant-killing Aikido line-stage amplifier, the above lists of parts will help you design an Aikido kit that includes everything you need to populate the PCB. Buy just what you need and save. Start with a pair of single channel Aikido amplifier PCBs for octal dual triodes, such as the 6AS7, 6BL7, 6BX7, 6SL7, 6SN7, 12SL7, 12SN7, 12SX7, 5691, 5692, 6080, B65, ECC32, ECC33… then add what need to populate the the two mono boards.
The boards are four inches by six inches, extra thick (0.93"), with 2oz copper traces, with five mounting holes. Boards are made in the USA and come with a user guide booklet, which holds schematics and recommended part values and design examples.
All that is needed to finish the entire line stage is a chassis, power supply, volume and input selector controls, and a handful of RCA jacks and hookup wire. Although the Aikido PCB kit isn't all that is needed, it is a great start.

Accessories
Four Tungsol 6SN7s The old Tungsol name is back—as is much of the old glory. This new production 6SN7 from Russia is definitely an upgrade from the other 6SN7s in production. $69 for four 6SN7s. |
Resistor pack All the necessary resistors to populate the PCB. Resistor pack includes multiple values for the cathode resistors. Choose between two types: carbon-film, 5%, 1W resistors and metal-film, 1%, 1/2W resistors. At least 44 Resistors altogether. $10 |
Supporting Capacitor Pack Four Wima MKP10, polypropylene capacitors: two 0.68µF 400Vdc & two 0.33µF 630Vdc. Four electrolytic capacitors (two for heater element shunting and two high-frequency capacitors for optional cathode resistor bypassing; high-quality Panasonic electrolytic capacitors are supplied). |
Four ceramic PCB-mount tube sockets High-quality, PCB-mount, ceramic tube sockets work beautifully on the PCB. $10 for 4 sockets. |
RTI Audio polypropylene-film Capacitors New RTIE Audio polypropylene-film coupling capacitors. This is an amazing sleeper of a capacitor. It is made in the USA by RTI Electronics, a 27 year old company that is, as RTIE likes to say, "an industry leader in the design and manufacture of
high quality audio/video Teflon capacitors." Which is true, as many high-end capacitors, no matter how labeled, are actually made by RTI Electronics. A huge upgrade in sonics over typical polypropylene coupling capacitors. (Obviously, the 12SX7 is not included, but shown to give a sense of the part's size.) $20 for two capacitors. |
Two 0.47µF PIO capacitors Two K42Y-2, 0.47µF, 500V, 10% PIO (paper-in-oil) coupling capacitors. Russian made and built to tight military specifications. Painted metal case houses foil/paper-in-oil capacitor. Here is one review from the web:
"After extensive testing between Rob and myself on several MAX builds, it is apparent that this cap provides an optimum choice for use on the MAX - neutral, smooth mids and highs, with an extended but flat high frequency response, and no loss whatsoever in the bass frequencies." http://www.diyforums.org/MAX/MAXk42.php $10 |
Ten Stand-Offs Securely mount the PCB with these eight sets of stand-offs. Each set includes top and bottom screws and two soft rubber o-rings. Might seem expensive, until you price each of the pieces at a hardware store. $10 for ten sets of stand-offs. |
Output-capacitor rotary selector switch Need a rotary switch for switching between the two coupling capacitors? Four-pole, three-position, non-shorting switch and some hookup wire is all that is needed. All four coupling capacitors attach to the PCB and the two channels output connect to either coupling capacitor C1’s or C2’s or both capacitors in parallel. $6 |
Super Strong Tape Five inches of 3M brand super-strong, double-sided, indoor/outdoor tape—an excellent solution for holding large capacitors to the PCB. $1 |
