I use a Unison research triode 25 and a Naim 5si. I prefer the tube amp. But the power tube on the tube amp El34s seems to just last a year and then one tube usually blows tripping the internal fuse and send the Unison amp to the shop for $300 in repairs and new tubes. Does any body know whether this is normal. I am very proud of myself for switching to the naim before the tube blows. How long do El34s last.
