Twinings Tea Box 12AX7 Tube Preamp with Remote 5Y3 PS

This is my second build of the Twinings Tea Box 12AX7 tube preamps with separate 5Y3 valve rectification. Others I have built used an internal or remote SMPS. This build used the massive and expensive Jensen copper, paper and oil caps. Silver wire, WBT silver solder, Solen Teflon caps (feedback) component-2-component wiring make this an exceptional build. There is no cct. brd. A remote PS with valve rec. (Ozzie 5Y3) and Hammond power transformer and 12H choke provide very clean robust power to the preamp Tea Box.

The sound is very 3D with sound stage deep and wide. The full passion of the music comes through with staggering detail making most instruments (acoustic anyway) sound very different. This build has been commissioned by a very astute audiophile in Denver, Colorado. I know he will be pleased. It goes with well used AWA (Amalgamated Wireless Australasia) 12AX7 valves, rare but sweet sounding.
