Does anyone here own a smart astro and is good with electronics?

[Arne]

I found out that the smart astro was originally planned as an rgb lamp featuring  2 red 2 green and two blue led's instead of 3 red and 3 blue led's. The circuit is prepared to support this and has two ways of populating the board and there are two jumper resistors called opt0 and opt1 and also there are solder pads for a third transistor and some pads for additional resistors.. Some of the changes that have to be

made are obvious like the third transistor and a third 1k resistor but there are also some options which arent quite as obvious. Would anyone be able to analyse the circuit and tell what exactly has to be done in order to male it rgb?
