KT-88EH in SF power 2

Tubes Asylum

Questions about tubes and gear that glows. FAQ

Hello everybody, has one of you ever experience a blue light shinning from the tubes after 2-3 hours of normal utilisation?
Blue light seems to come from inside the tube, and all bias on them are fine.
This can be seen only in a very low ambient light, and it is on all the octet i'm using....
I don't think the tubes are finish, the bias ajustement is very easy to do. the tubes might have less than 300hrs.
On a Sencore TC136 emission tester, they all test great 105%.
Thanks!
