Fans of the classic and hard to find Roland TR-909 drum machine are about to have their worlds rocked. Today E-licktronic, the maker of the Yocto Roland TR-808 clone, teased the Nava v1.0, which they describe as a “1:1 clone of the analog section of the Roland TR-909.” Nava v 1.0 will be sold as a DIY kit with all rare transistors and ICs, potentiometers, switches and preBurned µC. The Nava kit is expected to be available April 25 for €319,00. The Mouser part is priced at US $183.73. Case cost is TBD. The kit includes:
2 x PCBs: the Mainboard and the IO 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 origianl 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 Potentiomètres 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. The only component that you must get is a 15VAC supply 1000mA, the same used for the Yocto v1.0. A screen printed aluminum case will soon be available on the forum.
