Hello everyone. I have been listening to the amazing bottlehead crack for months but have recently upgraded to a 5998 tung-sol tube.
The seller sent two 5998 tubes, one sounded perfect/amazing/divine, the other was in worse shape, had glass parts inside it and sounded noticeably worse. With both tubes tough, I had a few gassy sparks the first time I used them, but now it hardly ever happens (burn-in?). I ask him to get a refund/partial refund for the glass shard damage and he is saying that my amp (the bottlehead)
"is designed around the 6080 which is not equivalent to the 5998. The bias set up needs to be different. The sparks are not good and can damage the amp, tubes, your phones or worse your ears. The newer 5998s from svetlana (winged c) may handle more voltage."I thought the 5998 were the preferred tube for the bottlehead though? (if one can afford/get them at least). Is the tube seller right / wrong? Can bias be adapted for safer usage with the 5998 tube?
Thank you for any help,
Regards and thanks
