BassmanBruce Posted April 25, 2013 Share Posted April 25, 2013 I have had a pair of 1980LaScalas now for the best part of a year. Replaced the mid and tweet diaphragms and updated the caps in the AA crossovers. One of the amplifiers I am running is a pair of Dynaco Mark III's. I have upgraded the Mark III's to the Poseidon driver board and like the Janzen Superior coupling caps in them. Here is my question- What is the better sounding output tube to run in the Mark III's powering the LaScalas- The GE 6550a or the Tung Sol 6550 (USA). On my last pair of speakers, a 3 way transmission line speaker the GE 6550a won out in a listening test. I let one pair of my Tung Sol 6550's go so I don't have enough TS 6550's to do another listening test with the LaScalas without buying another pair of tubes. I know a lot of Klipsch users use the Dynaco Mark III, and an opinion on this would be very helpful. Thanks, Bruce in South Carolina Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted April 25, 2013 Share Posted April 25, 2013 Used to listen to MarkIII's driving Khorns and liked the Tung Sol 6550. Didn't compare it with that GE, though. It's a can't go wrong choice. Quote Link to comment Share on other sites More sharing options...
