No problem. You should get 20,000 or more hours from them. They are not being used as power tubes... the amplifier section is a MOSFET stage. So, there is almost no change in output on the 300B tubes, they are being used in the preamp section.
Volume playback and tubes lifespan
Hello,
I am not much technical . I own a Vinnie Rossi Brama Integrated Gen.2.
I wonder if listening at rather high volume , will reduce the tube ´ s lifespan compared to listening at low volume .
On internet web site : ´´ .... Here in the Brama, the 300Bs don’t need to be biased as hard, since they are only being used for voltage gain (not power output) and are under dramatically less stress than if they were directly driving speakers. And that means they can run while horizontally entombed inside the Brama’s casework. There’s a reason you normally see power tubes such as the 300B out in the wind, and that’s because when driving speakers, they generate a ton of heat and must dissipate it. ´´
´´ ...the Brama is fronted by two 300B tubes, one for each channel, in the preamplifier section ´´
