I thought both the 7308 and the 6922 were 10,000 hour rated tubes. The differences, if I remember correctly, were that the sections in the 7308 were guaranteed matched to with 10% from the factory, and they can take more voltage on the plates than the 6922.

You're right. I must have been thinking about the difference between the original 6DJ8 and the 6922. Having said that, ARC used to recommend changing after 5000 hrs on their old web site.

Eli to vet this? Small signal tubes tend to last a long time, power tubes and rectifiers less. - Timbo in Oz 16:25:36 04/18/15 (2)
