The New Tube Mic Power Supply
Our 12-251 tube mic kit has been getting fantastic reviews (and winning shootouts). It has a fully custom circuit and transformer, with an excellent tube and capsule. The one leftover piece of the original Chinese-made system was the power supply. It worked OK, but wasn't great.
So, we made a new one. Or more accurately, we hired a well-known tube mic power supply expert to make us a new one. (Because any time you're playing with hundreds of volts, you don't want to do it wrong.)
Pictured here is the first production prototype. We will sell it as a finished product, and as a DIY kit -- complete with Neutrik connectors and a powdercoated case. It will be an upgrade option for our tube mics and kits. So, if there was ever a question about whether our 12-251 kit or V-12 tube mics compete with all the $1500-$2000 commercial offerings, there won't be any more.
