Geesh, spoke to soon. 3 out of 4 Gold Lion reissue's failed within days of each other. Think I got about 7 months out of them. Liked the sound, not happy with reliability.
Fred, I was just curious: where did you buy those GL's?
As I said, I've not had a chance to compare the GL's w/ the Penta KT88SC's (it's about 50/50 which one people like better) but I've never heard of reliability problems with the Pentas. You might want to give them a try the next time. . . . . . . and they're a little less money too!
Hi Gerald, I am also running tung-sol 6550 in a Cayin A-70T, and find the bass to be lush, mids and highs are sweet. I tried EH Kt88 in the cayin and found the bass to a bit thin and the highs a bit grainy.
I have the Genalex KT-88 reissues in my RM-200 and they work beautifully. A big improvement over the original tubes, as promised. Mine were factory matched, too.
The Gold Lion re issues have a tighter and deeper bass in the A70 than the Tungsol reissues. A leaner but not a thin or cold sound (they are not as lush).
