Single-channel Aikido amplifier octal printed circuit boards New Rev.A with more options and new ventilation holes!
Product Description
A new single channel Aikido amplifier printed circuit board for octal dual triodes, such as the 6AS7, 6BL7, 6BX7, 6SL7, 6SN7, 12SL7, 12SN7, 12SX7, 5691, 5692, 6080, B65, ECC32, ECC33…
Why a mono version? Several reasons come to mind: some have returned to the purity of mono hi-fi (half the cost, half the headaches), on the other hand some are running three- or five-channel systems and they require a single Aikido board for the center channel, some need a single microphone amplifier, some cannot use the larger stereo boards in their high-jacked cabinets, some are building monoblock power amplifiers and the stereo boards would be half wasted, and some might be building a stereo amplifier that will not work with the long stereo Aikido PCB, but could accept two smaller PCBs.
The board can be used with either a DC or AC (if the heater shunting capacitor is left off the board) power supply (6.3V or 12.6V) for the tubes' heaters, so that 6.3V heater tubes (like the 6BX7 and 6SN7) or 12.6V tubes (like the 12SL7 or 12SX7) can be used. Both tubes must share the same heater voltage. For example, 6SN7 for the input tube and a 6BX7 for the output tube can be used, although they differ in heater current draw; a 12SX7 and a 6SN7 could not be used, as they differ in heater voltage; however, a 12SX7 and a 12SN7 could be used.
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 schematic and recommended part values and design examples.
Limited quantities.
A package of four ceramic tube sockets for this PCB is also available.
