That is ok, to bring up the console you open your Tekkit launcher, click on the little cog on the Tekkit classic picture, and there should be a couple of options. The one that you want to click is the show console setting. This will show you everything that is going on in the game while it is booting up and in actual gameplay. Also are you using a texture pack?
EDIT: Sorry, you want to click the cog top right of the main console!
