Well that's good we can do a compare, I'm hoping the tung sol and the rca arrive today, and next week, hopefully!, arriving a Chatham 6as7g, Rca 6sn7gt grey glass, Sylvania 6sn7gt grey glass and a Syl 6080wb, so I should have plenty to keep me out of mischief!.
On another note I'm experiencing the infamous DV hum, it's quite loud even stood 6 feet from the unit, however once the headphones are on and music is playing I don't hear it even in quiet passages, is this similar to others experiences?, I am intending to take out the power tube and burn in the driver, it will also be interesting to see what happens when the old stock tubes arrive.
