We are happy to release for preorder the new S.E.X. 3.0 kit.


The new S3X uses a 6FJ7 tube. This is a compactron version of the venerable 6DN7, which has become very difficult to source in quantities after selling the S.E.X. kit for over 20 years. The 6FJ7 is the same tube, just in a different envelope with a different pinout.

The S3X also has a new universal power transformer, so you can order one with the confidence that it will still work for you if you need to move from a 120V country to a 230V country or vice versa.

The S3X kit has a new layout and a new manual. It's easier to build than the previous version.

And we addressed a request for a little bit lower noise floor to accommodate users who have extra sensitive headphones. I believe the final result was a noise floor that measured in microvolts.

We're taking preorders for the S3X kit, with an estimate of shipping to begin in 8 weeks. The preorder special price is $459, 15% off the regular price of $539. This offer is good through next Thursday, November 24th. The link to more info is below:
