Building yet another mono triode Salt Cellar wine box amp I had to make it different. To make even simpler this time just one tube, the 6EM7, which has two triodes in the one bottle. I'm told its like having a 6SL7 and a 45 in the one tube. Once more an external (but different) tranni box was used. This one also works with my two wine box 6L6 SE UL amps.
Again all parts came from da lab. That part of the Salt Cellar initiative was flowed strictly. How simple with just one tube and an Alps stereo attenuator. The output of the attenuator is coupled with two resistors for a mono mix. Strictly using parts on-hand I use a SS double Pi rectifier brd. I had made many years ago. Add a big 10H 125mA choke and yet another stage of filtering you have a dead quiet "is it on" quietness.
A different finish here from using a staining varnish and again an old world look and feel. The knob goes on top otherwise it would have looked a little baron. All wiring is via solid core Cat 5, motsly as twisted pairs. Early days the amp sounds good but does it compare with the original SC 807 amp. Time will tell.
