Want to build a tube preamp

[gayler]

So I finally got around to checking out an old organ amp I've had laying around. It has no preamp with it so I pluged in the line out of a solidstate amp and with the volume all the way up it sounds like a very quite bedroom amp.What I would like to do is build a preamp for it, maybe two, one fenderish and one marshallish. Are there any kits, or plans for this? I checked around and could not find any on the internet. Thanks! Oh by the way it uses two 6L6's a 5U4GB and a 12ax7 pi.
