I was recently invited by Jeffery D. Medwin to participate in a very unique opportunity for builders of SE tube amplifiers.
Some very special "magnetic components" were designed by Dennis Fraker of Serious Stereo for use in SE tube amplifiers and offered as part of a group buy.
It was a no-brainer to take advantage of this offer and get an edge on other builders.
I will provide more details once I get the parts and begin experimenting.

Update 1/6/2020 : no word from JDM on the status of DF's new magnetics.
If I get any new information, it will be posted here on the DT667 webpages.
