Since Audio karma is now hosting the forum for GF, though it would be a good time to start this thread. I recently purchased some black bottle KT-88 tubes from Ian for my GF-A88 amp. I'm also running the TJ Full Music 12AX7 preamp tubes in place of the shugaung stock, and just (will be getting them right away actually - literally -they're here at the post office and I'm going once this post is done) getting some NOS Sylvania Chrome Dome 1940's 6SN7GTB's (supposed to be the best sounding GTB's according to those in the know). I'll post pic's and impressions soon. Just wanted to get this thread started. I will say that so far very impressed with the Treasures. However, I only have 15 hours on them so far, and it could a while before I get a chance to put more on (#1 we're in the middle of a heat wave, listening to tubes with no A/C is not my idea of fun and #2 I'm in the middle of a backyard project which I also have to get back to right away). I am keeping a diary on these tubes though, and will make a rather long post as these thing break in. I'll make my initial listening report at about the 100 hour mark. Hopefully it will help out anyone looking at getting these tubes for their own gear.
