Unless you havent been visiting here lately and didnt see it, 'Wild West' recently acquired a G-9000. He posted the whole story of how he acquired it for a great price (great meaning inexpensive) as well as posting photos. The bulbs were out on his and he had them replaced. So, I think an easy answer to your question is to simply contact WW for the info on the bulbs.
To read WW's post on the G-9000 and any other mentions of this model, avail yourself to using this Site's Search option which will bring up all the past information on it.
