We are now posting and maintaining a list of noise measurements made on current production (and a few new, old-stock) audio vacuum tubes. It includes popular types such as 12AX7, 12AT7, 5751, and 6DJ8, and it will include more in the future. See our Downloads
page for details, and let us know if there are other brands or types you would like to see included.
The Minotaur now has a tempered glass window (in place of the original polycarbonate).
Both versions of the Minotaur are available. Please allow 3 business days for final checkout and burn-in. We don't charge until we ship. Thanks!
Our small initial production of the Minotaur has sold out (both balanced and unbalanced versions). We expect to have more units available for sale in January 2015. Contact us if you are interested!
The standard version of the Minotaur is now in stock. The balanced version will be available in Nov. or Dec. 2014.
I've gotten some great positive feedback from our beta-testers, which has been very helpful for improving the product version of the Minotaur. Based on their requests, I'll also be introducing a version of the Minotaur with true balanced inputs. Product availability (of both balanced and unbalanced versions) will be slightly delayed, until Nov - Dec 2014. Please contact us for further information or to reserve one.
Pre-production samples of the integrated version of the Minotaur are now in beta-testing. The first production amplifiers will be available for sale on this website in October 2014.
