Recommended tubes for LTA Preamp


Hi All - 

I recently upgraded my LTA Microzotl preamp to the Level 2. I see myself having this component for a long time and don’t anticipate ever wanting to replace it. 

I’m planning on purchasing some back-up tubes for it, though. I was wondering if any LTA preamp owners out there wouldn’t mind sharing their experience with different NOS tubes for the LTA.  LTA currently has Brimar and GE NOS tubes in stock, but wanted to see if anyone might share their own experiences tube rolling with the LTA preamp. 
 

Thanks in advance!

I replaced the 12AT7s with Telefunken ECC801s. I replaced the 12SN7s with CBS/Hytron VT-231 per a recommendation from Brent Jessee. I definitely recommend reaching out to Brent. He is incredibly knowledgeable and extremely helpful.

In my system, the tube changes were a dramatic improvement in sound. There was better top and bottom extension. The sound got even more dynamic. It wasn’t cheap, but the rolling to me was well worth it.
