12AX7 Valve Preamp in Twinings Tea box

This is the fourth 12AX7 tube based preamplifier kit I have built. A Twinings presentation tea box was used as the case (similar to my Gwado CMoy / Grado RA1 Headphone Amp) with a remote PS. Cardas caps were used, all pure silver wire, silver solder, Alps blue velvet attenuator and 4 oz brass knob. The rear has a terminal strip for all the connections and the case is lined with a tar and aluminum film. The power supply has speaker absorbing vinyl lining it to ensure the switch mode tranni remains quiet.
