12AX7 Valve Preamp with Jupiter Beeswax Caps

I have made a number of these kit two stage 12AX7 valve preamps in all sorts of enclosures. I have employed a wide variety of different caps in the signal path including, Sprague orange drops, Cardas Golden Ratio and standard metalized polypropylene. In this build I have used the Jupiter beeswax and paper caps. I have used these caps before in SS preamps and found the sound very natural and liquid. The larger components have been placed on the underside of the cct. allow the valve to project through the enclosure.
