Just finished my Bottlehead S.E.X. amplifier - Album on Imgur
I have started to assemble my Bottlehead S. Single Ended eXperimenters kit. This amplifier drives headphones and sensitive speakers. I bought the kit including the impedance as well as the C4S upgrade options. Here are pictures of the build: Impedance switch Constant current source Top plate Completed underside Upper side.
Y es indeed folks, I am a very SEXy man. I built this some years ago, but it's still an active product and long overdue for a review. My particular unit uses Magnequest upgrade iron, and then sold as a standard package direct from Bottlehead but now you order separately from Bottlehead and Magnequest.
