"Grace" - 6SN7-SE preamp




I would generally never post an incomplete project but due to extreme interest in this project, from my retro-thermionic facebook page, I have decided to post. The tubes are limited edition Psvane Treasure 6SN7-SE  globes or bulb shaped. They are strikingly beautiful with their gold metal and ceramic bases, quaint shape and gold markings. This build will not only be about a great performing preamp but an extremely beautiful build. 

Keeping as much gold as possible in parts selection the knob attached to a 22 step stepper attenuator is 4oz of solid brass and gold plated. The six RCAs (two selectable inputs) also gold and the standard "retro-thermionic" name plate polished brass. The white sprayed chassis and wooden cheeks complete the lush look. The cheeks are rubbed with a finishing oil to lift grain and protect. A XLR connection on the back will bring in power required. Next phase is to wire the preamp.
