DIY Low Gain Tube Preamplifier

[Eric.DeYoung]

Well, I'm in the middle of a school semester, and I'm in desperate need of a fun project. I'm looking to build a tube preamplifier - but I would like a low gain (0db to 12db or so) design so that I can insert the preamplifier between a line out from my sound card, CD player, etc. and my receiver. I've always wanted to try tube gear, and I think that this would be a great way to get started without having to spend a huge amount of money on huge power transformers and output transformers. I've been looking around online quite a bit, and found a couple designs such as http://www.shine7.com/audio/6922_pre.htm
that I really like - however the gain is much to high for my liking, and it seems that some people aren't too fond of the cathode follower arrangement that acts to lower the output impedance. Do any of you have some links laying around that might be what I'm looking for?

Thanks!
Eric

Google up the Bottlehead forum, and you will come across the tube enthusiasts. You won't find many here; last time the subject came up it wasn't pretty. Once there, you will (hopefully) learn the relationship between transformer costs, and gain. Just FYI, I changed to a higher gain pre amp, and I really like it. Nah, to be quite honest, I LOVE my tubed pre-amp, but, it was not cheap. Think in terms of several thousand. Never let anyone stop your learning curve.

I am considering this.
