"Oceans" - 6SN7 single stage preamp

 












This build is very similar to the original Ocean but the tube is a new JJ 6SN7GT.  Nice so far but all parts need a 50 hour break-in. Choked PS double Pi with 5H choke. Cast Al enclosure, Alps Blue Velvet pot gold vernier knob, snubbed NP Cks, silver plated fine wire for hookup. HT=260V, Bias=3.8V. All metal film Rs. Three inputs on this one. And Ocean Blue Hammertone finish.
