I gave a magazine that has a construction article for a 19-inch rackmount unit that contains two Altec tube preamps in it that look really easy to build on Turret boards, over here in Australia, there's an online company called Evatco that sell some nice FR 4 Fiberglass Tagboards that have about 28 tags on each of the two long edges of the boards, great for building stuff like this.
