KT66 loosing its getter

[ixe13]

Hello everybody,

I've got these two Sovtek KT66 working fine on my Quad II. I bought them brand new last August. I noticed that the getter in somehow slowly disappearing in both tube.

Should I be concern?

They work fine, the sound does'nt seem to be affected. all the voltage is within spec.
Bizzare...

they're on the same Amp by the way.


Thank you in advance for any advices.

Yves

I'd have some replacements ready.

Thanks SY for your reply,

Time to get a new pair. It's a bit annoying that these tubes are going down the drain so fast...

By the way, I made a mistake, the tubes are not SOVTEK but SARATOV.

Wouln't want people to get the wrong infos, my apologies to all.
