6H30 Tube Life in ARC

Posted by Barry on February 27, 2017 at 17:48:43:
ARC recommends the Sovtek 6H30s supplied in their Ref series of preamps be replaced at 4,000 hours. I replaced mine about that time, but they may have lasted longer.

I believe the NOS "super tube" DR version's life was rated to as high as 10,000 hours.

Victor's certainly the expert on the DR tube parameters.
