Nava v1.02 kit

The kit includes:

• 2 x PCBs: the Mainboard and the IO Board
• 2 x MUX/SH board
• The µC, a Atmega1284P pre programmed with Firmware Nava v1.0
• 3x program EPROM 27C256 with the sound of HitHat, Crash and Ride as those present in the original TR-909.
• 36 x M5218L Mitsubishi. Those are the original TR-909 OPA
• 2 x HD14006BP 18 Bit static shift register used to Noise generator
• 1 x AN6912 Quad comparator. HandClap envelop generator identical to that of TR-808.
• 1 x BA6110. This is the only component that we have replaced the original TR-909. The original HandClap VCA is a BA662 manufactured by Roland, but today very expensive and rare. After several sound comparisons and operating the BA6110 makes an excellent substitute for BA662.
• 19 x 2SA1115-F PNP transistors
• 56 x 2SC2603-F NPN transistors
• 4 x 2SA798 PNP Monolithic Transistor Pair
• 2 x 2SD1469 NPN Small signal transistor
• 2 x 2SC2878 NPN Epitaxial transistor for muting application
• 27 x Potentiometers (all necessary controls for the construction of Nava v1.0)
• 19 x Cherry switches with whites caps
• 17 x illuminated square tact switches

All other components to complete your kit are available in this Mouser BOM:  http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=26a285d084 .The only component that you must get is a 15VAC supply 1000mA, the same used for the Yocto v1.0. A screen printed aluminium available on the forum or by Erica Synth. You need also 25x small knobs and 2x big knob.
