If you carefully read the pages on the Don Sachs website, his custom phono preamp, line stage preamp and 60 wpc power amp are all based on the circuit boards he gets from VTA - http://tubes4hifi.com/
You can buy all of these things as kits from VTA, or have them assembled by VTA as well, for quite a bit less. What Don gets you is a much better look and possibly some minor tweaks.
