If you're looking for a project, I have a Bottlehead Crack I built about 5 years ago sitting around getting no use. The caveat is that there's an issue with the left channel. I believe it's related to a faulty connection on the 9-pin socket, but have not tried fixing it. I also have a speedball upgrade kit that has not yet been installed. LMK if you might be interested - I'm happy to send photos along.
