January 19 @ 12:00 am - March 16 @ 12:00 am

The October Muse Tech Talk is about a great DIY opportunity.  David Hicks writes: “I was fortunate enough to take one of Ed’s phono stage building classes at the Randall, and I can say, I learned a lot, met some great people who became friends, and had a ton of fun and ended up with a terrific piece of audio equipment.”

Edwin is announcing a new amplifier class:

I am pleased to announce a new tube audio DIY class at San Francisco’s Randall Museum. It’s been a few years since I taught one of these DIY classes, but I’ve just created a new project that I want to share.  For this class, I designed a push-pull EL84 stereo amp “The Randall IV”. Beware that this is not your run of the mill EL84 job. The goals of the amp are; sound as close to a live performance as possible, keep the cost down, minimize the component count so that it will be easier to build, must look pleasing both inside and out.
