先来看看What's New ----
1/18/18
Thank you for your patience. What can I say, I've been very busy. The results will be out soon.
We have a new amplifier, the SIT-3, which will be the last of the “VFET” type amplifiers using the SIT power transistor custom made for me by SemiSouth, unfortunately no longer in business.
Originally I did not expect to have enough SIT transistors to create a third amplifier. I set aside a sizable quantity for warranty repair, but this has not been needed, freeing up parts for a new design.（看起来质量还不错？）
The SIT-3 is a stereo single-ended Class A amplifier with more power, lower distortion and noise, and better damping than its predecessors. It features the single SIT-1 in a unique circuit using “Common-Drain” mode without feedback, and has the ability to drive lower impedance loudspeakers.
Also, there is at least 1 new version of the B1 preamp - “This time with gain!”
New on the DIY front, there are several new projects:
DIY versions of the analog active crossovers for the the Linkwitz LXmini and Lxmini+2 loudspeakers using discrete JFET stages, as well as other DIY crossovers and equalizers in various flavors.
New DIY Sony VFET amplifier channels using up the last quantities of the Sony VFET stash from Singapore. Like the SIT-1 projects, the VFETs have been freed up by the reliability of the previous projects. This time, we will do something very cool with them.
Look for all this in March-April.（很快了哦？）
